What effects does childhood abuse cause later on in life?

I think I may have been abused in the past, but not by what people think of abuse, but I think it has actually messed with my head, in the past I was taken into care at 6 years old, I was away from my mum for 9-10 years before being able to see her as much as I wanted, I was only aloud to see her once a month and never saw my dad.

I am actually a bisexual, but what I find most attractive is men at the age of 50-80, very rare I like an 80 year old but there's some that I like, most are not for me, I am however only 22, but am most attracted to men around 60 years old, I don't know what it's about but I think a lot of what comes into it is that I was without a father and a loving family for my childhood, I never felt that connection I do with my mum now.

I don't understand the reason I am actually attracted to older people, I think objectively they are quite hot, but that could be just be from what's happened to me, it could be what I was born interested in. But from my past I would say that foster care did actually affect me, it's painful when you don't have a genuine family around you, it's not the same with foster families.

My past has also fueled my hatred of society, on a very fundamental level I think I have a grudge on society, it's like from my past being rejected by my family and not having anyone there for me, has made me feel bad about people in general, I am actually very pissed off with most and are always skeptical about people being good, it makes me anti social and condescending to them, it makes me want to push myself away from most people, I do not like the average man, people are generally only out for themselves and are quite selfish though, not all but most.

Well, hello there,
First of all, I have to mention that English is not my mother tongue, so I might confuse the meaning of the words, but I don't think you can call your situation / your past "abuse". I would rather call it "neglect" (which can have the same symptoms and / or medical conditions as abuse).

The symptoms or effects, what your asking for, are for me more or less some form of anxieties: fear of men who look similar to my offender, fear of proximity of strangers (not in crowds, but e.g. within a conversation), and bad dreams.

Also I'm insecure, if I'm able to have a sexual relationship in the future (my teen relationships are some more years ago), because of the fear of proximity, despite I really want to have and desire such a relationship.

I can relate to the attraction to older men. I for myself too can find everything up to 60 really attractive, I also already fell in love with men, which could have easily been my dad. To a certain degree, I don't think that the age really matters (at least regarding attraction) especially when the own sexual development process has started (I know, I fell in love with notably older men around the age of 12-14).
If it is really the missing father in your case only a psychologist will be able to tell you.

But I make a difference between finding hot, attractive, whatever and really falling in love / wanting to have a relationship with. Relationships, at least I think, will only work with max. 10 years apart. Maybe there are a few with more difference, but the majority of won't last long. Think on the different interests and behavior.
By the way, I'm also 22.

Yeah, I know the hate on society myself quite well, but different than you. I've allways felt different than others, since I can remember, I was often a outsider / a missfit. I was overwhelmed with the big decision of a right job, in the first one I was bullied the whole time, and now, in the second one I'm badly strugling with my emotional chaos, despite I don't really know why I am so depressed.
I'm feeling like I don't fit into society - as if they want to push a cube through an equal, circular opening.

My big problem is, that I hardly have time for the things I can buy with my money, which again I get for "giving" my time for someone else... society is not that different from a bee hive...
I think you have trust issues.That's why you are so skeptical and anti-social. Do you want to change that ? Or why did you address that ?

Here have some *hugs*

I suggest do some reading on neglect and also "attachment theory".

That period of bonding with mothers sets us up. Without it we are a little different.

Knowledge is power.

Good luck
