What is your definition of psychology ?

I find that my hardest days are days like today where I wake up just loathing myself. From the moment my eyes open the flood of negative thoughts drown out any positive I can see. In these times even my children laughing and smiling outside my bedroom door cause me tears.
I feel alone, which is hard to do when you live with five other people but there it is. I can never seem to pin point just why some days the pain is so overwhelming and all consuming that lasting the next five minutes seems impossible.
I am worthless, unloved, and discarded. These are the thoughts that are an unending cycle in my mind. The more I attempt to distract myself from these thoughts the more invading they seem.
Any advice out there?

Recently I was at a party where many people were intoxicated, myself included. There was a lot of dancing and girls grinding on guys and groping and whatever else happens on a dance floor probably happened here. While at this party I talked to a lot of people and remember every detail I just didn't have the proper control of myself as I was heavily intoxicated. Nearing the end of the night I was approached by a boy who somehow knew me although I wasn't sure who he was. I walked away but he was insistent to talk. He pulled me closer to him and kissed me. We made out and everything was fine. Now, at this party people were staying in tents or their cars on the property and I had a tent with my friend. This guy that I was with asked me if I had a tent and I said yes, he took that as an invite and said "that beats sleeping on the floor". I wasn't 100% comfortable with him coming back with me but, I am the type that has a hard time saying no when someone says they'll be sleeping outside or whatever else. So he followed me back to my tent and I warned my friend before he came in. I was quite tired as it was very late and I was ready to go to bed but this guy was grabbing me and kissing my neck and wouldn't stop. I would push his hands away and he would tell me to "stop" or "just let it happen". Although, I continued to ask him to stop he continued until i sat up and said he needed to stop. At that point he got angry and told me that I was being a tease and i needed to "get him off" before he could go to bed. I said I just wanted to sleep and was feeling quite emotional, he was about to leave when i started to cry, as I was just yelled at when I didn't want to have sex with him. He told me it was fine and we would just cuddle and sleep. When we were back under my blanket he started at it again and i continued to tell him to stop as i still wasn't wanting to have sex with him and he started getting angry again. He was kissing me and had his hand wrapped around my neck. I was afraid of his anger as i didn't know him nor what he was capable of and i didn't want him to wake people so i complied and told him that we could have sex. About half way through i started crying and he told me if i was loud he would choke me harder so i sat there and let him do what he wanted.

I complied and told him it was okay for him to do what he did although the multiple times i said no and i felt pressured into this situation. It continues to haunt my dreams and I don't feel like myself anymore. But, was it rape...

Ok, so I've been up for about a half an hour since this "nightmare" that I had. I don't remember the beginning but, it was short, extremely vivid and has me a little shooken up.
Ok, so I was at my ex boyfriends house. His mom had this extremely amazing camera which she let me use to take some quick pictures of. So I proceed to the back door, snap a picture of the sky from the back porch. Then I end up towards the end of the back yard by the fence while holding the camera on an angle. I take a picture of the backyard and the back of his house and review the picture. There, I see a little girl, in a purple dress with curly long brown hair bending over picking a dandelion. I look away from the camera in awe checking to make sure I'm not seeing anything, but low and behold I am, I just captured a ghost on camera. She was freakishly see through but yet so bold. I then run around to the front of the house avoiding her area. I run in the house and show the picture to my ex boyfriend telling him "do you see anything wrong in this picture!?" He then says, no. Then I zoom in on her, and he says "wow that's insane" and calls his mom over. I then show her, and it begins to get darker and darker in the house while she just has a blank stare on her face. She runs upstairs disappearing saying, "someone turn some lights on in this house" meanwhile, I literally cannot breathe, I am literally having a panic attack in my dream as my ex boyfriend picks me up and holds me. I then awaken from this physically terrifying "dream" with my mouth open, and I'm stuck. Literally stuck for twenty minutes in a daze and I cannot move. After I actually come to my senses I'm scared, terrified and in a lot of pain. As of right now, about an hour after my dream, my legs hurt really bad. Like they got ran over or something. A very dull pain shooting from my hip down to my big toe. I have never EVER experienced a "dream" like this before, and if anyone has any insight, or opinion as to why I woke up in pain from this, it would be appreciated. I'm honestly still in shock from how vivid this little girl was. I'm too afraid to go back to bed and rest peacefully.

How are mental diseases like ADHD even thought about? What are people thinking when they categorise someone in the ADHD category? Doesnt the society actually decide this? "Okay, youre hyperactive, i bet you have ADHD". Im an indian and ive seen a lot of people who may have been suffering from ADHD according to the intn guidelines but they lead a normal life mostly. ADHD medication is basically a drug, amphetamine. So, enlighten me pls? Btw, i dont have ADHD. Its just food for thought.
