Angry with self and the world

I am suspecting bipolar and/or depression for this, hence for posting on this forum.
This is a very long story about my problems, so excuse the mountain of text. I hate disclosing my true feelings to anyone, but I feel that this is a needed step to take in order to sort myself out before I can't take it anymore.

Before I start a few things about myself: I am a Humble 22y/o polite, respectful, responsible, accepting, honest, over thinking perfectionist. I would never describe myself as this openly in front of others, this is actually the first time and I know by the end of reading this you may think of me as an Arrogant and Angry person (a$$h0l3 rather), but in person I am not at all (maybe I am just good at hiding it idk). Also this "novel" was written over multiple periods to accurately contain all my thoughts/feelings in order to paint a bigger picture of my malfunction, so excuse me if certain parts seem to be trailing off.

Here it goes:
Since recent years I am angry, disgruntled, disappointed and lost on the inside. I feel without purpose and have zero clue what I want in life, not just career wise but life in general, too. Interestingly I feel good about being angry for the most part, well occasionally it depresses me too much and I usually go on a long road trip or hike by myself to feel better but I always go back to being angry and lonely.
I absolutely despise people my age and younger, (don't think much better of people older than me either). They all think so primitive, only caring about sex, money and getting the next "rush" in, whatever that maybe (parties, drugs, sex, booze etc). Everything in this society seems to be solely focused on those things mentioned: money, power and getting the next "high" which most often takes form in sex. Heck I am willing to even say that the desire for money and power is only there to be used to gain the next "high".

There is very little further insight to life and our surroundings, and only few think similar to me, and this makes me want every human to die for being so stupid and primitive. I may very well come across as arrogant here, but this sorry ass existence that we all live makes me hate everyone, I don't care about anything anymore, I just want to die at this point. I even like feeling this way usually! I think of my fellow human beings as lowly scum, and I just hate everybody. Now sometimes I get the odd emotion shift and I actually desire everything other people do too; a romantic partner, sex, happiness and overall a stable good life.
Heck sometimes I even get jealous of all the people being socially active, going to parties, being liked, being social, getting laid, getting drunk and downright silly and generally having good times, and sometimes I wish I could do that too! But these thought only last shortly and I come back to my senses and realize how primitive these things really are and how deep down I don't want them. Don't get me wrong, I don't have social anxiety, I have friends, I dated for a while, and if I really wanted all the things I listed I am sure I could get em with enough effort, but I just don't want them for the most part or at least so I feel now atm.

Please don't take this as a whine threat, because I understand my situation and know how I could get out of it, it's just I don't understand why I don't want to! I have no drive to get out and do normal everyday life stuff.

In all honesty after reading what I wrote so far I realize that I am largely consumed by jealousy of other peoples' lives; how they can be so contempt with going to work every day doing the same $#%^, every weekend partying (my age at least) and doing the same $#%^, being in the same place all the time doing the same things over and over and over. I don't feel I fit into this society at all if I compare myself to other same aged males. I am straight but don't oogle after women and don't only think of getting laid, I don't act like a complete idiot just to be funny. I think I am too serious in life, and this makes me not fun and therefore alone. Yet I don't feel like lowering myself to that primitive level just to fit in. I just feel purposeless in this universe and in this backwards society where materialistic gain takes precedence over knowledge gains, I guess that's just it.

Anyways ty for reading, writing this helped me clear a few things up, maybe someone out there feels similar or knows what's up. Maybe I have a mental disorder idk, let me hear your thoughts. If not, ty anyways! Sorry for sounding like an asshole, too, I am not like this in person. Everyone considers me a "nice guy" and a "good friend".
Meh, bollocks.

I can relate to your anger. I get angry when some person makes a false assumption, or someone who doesn't understand what I have been through that has left me with few choices but to be what I am.

The problem is when you are angry, your anger somewhat offends people who you are not angry with, and people who are not your enemies. The anger can forge new enemies that you otherwise don't want or need. You can't prevent getting angry about some things, but if you stay angry because of them then you get a cycle of positive feedback for your anger.

I'm similar, I think its mostly due to the fact that I'm so different and in the past when I stated my true feelings I was verbally criticized.

Well, luckily we have the internet where we can go to blogs, forums etc about pretty much every topic. So do what I do and spend a good amount of time (I mean hours and hours) to find places where you can discuss with other people about certain topics that at least sound interesting to you and are about more then "primitive" things.

Are people really such lowly worthless scum for going after what they want? We can't logically blame people for doing things that make them feel good when those things do not harm others- hell even you say you feel and sometimes want these things.\
You say that people are so content with their lives. You sure about that given that around 15% of people are on antidepressants, another 10-15% addicted to some drug, and probably another decent portion who aren't happy and for what ever reason aren't on a medication, or using drugs?
You do not control your feelings and to an extent your thoughts. We only control our behavior and from the sounds of it you do not behave like an a$$hole, that means you are not an a$$hole. Now if you start telling people that they are losers who deserve to die, and start doing things like injuring people then you are an a$$hole, until then you aren't.
