Well i'm 16 years old 3 months from 17 and I have never had sex before just to put that out there for now. I'm currently going out with a 13 year old (i know she's young) but is quite mature. I have an older brother that is 18 years old. I am physically fit and a very good sports player as I weigh only 135. I get pretty good grades in school as well.

I have been looking around on sites for help to find out what I can do cause I just feel horrible and sad all the time.
From one site I got:
Chronic or life-long (endogenous) depression is caused by trauma in childhood which includes: emotional, physical or sexual abuse; yelling or threats of abuse; neglect (even two parents working); criticism; inappropriate or unclear expectations; maternal separation; conflict in the family; divorce; family addiction; violence in the family, neighborhood or TV; racism and poverty.

Here's what I responeded:
Emotional – I just feel sad a lot of the time
Yelling/Threats of Abuse – I get threats and get yelled at from a lot of people from another town where my girlfriend lives.
Neglect – No-one really ever notices what I do since i'm like so to speak a "computer/game nerd", I really want to get into being a computer engineer so thats kinda why. No-one really cares what I do although it takes a lot of my time, all they do is make fun of me.
Criticism – Brother always tells me stuff I do is just stupid or is crap, parents think my gaming is a waste, I get made fun of for what I look like (hair and like acne mostly).
Innapproptiate or unclear expectations – They always tell me that I am really smart and should be like the best at sports, I’m not as smart as they think and I want to play for fun but people expect me to win at sports.
Conflict in the family – Me and my brother always compete. (Who looks better, whose more successful, whose better at sports/games, etc…)
Divorce – My mom and Dad got a divorce. I really like them both and I barely ever see my dad anymore since he live 3 hours away.
Neighborhood or TV – We have no neighborhood and barely any kids in town and TV is like the only thing to do inside. I live in a town of like 100-125 people.

I've had 5 girlfriends in my life. Four of them told me that they never did love me and they thought I was just a real jerk. I have a very low stress level because of it plus almost everything else. I'm quick to get very nervous about the slightest thing and I weirdly get like scared of being stressed.

I would like to know what things I can do to stop being so depressed since I have been to a therapist which didn't really help much since when I get depressed I get really anger and sad so I don't want to talk to no-one and since our family doesn't have that terribly much money but we get by all-right it probably wasn't the best therapist.

When I usually get depressed I always change it to something sexual. I cover up my depressions with sexual thoughts or doing things with my girlfriend. I don't want to do this when I get like "in that mood" I can't control myself or what I do. It's almost like i'm raping them which I really don't like at all. I know I have a lot of issues

Me and my brother have a lot of issues like we always compete and he always seems to be better then I am. Everyone knows him as the cool fun party guy and i'm the creepy little weird brother who sits in the house all day and has no friends. I have some friends but barely any. I get yelled at a lot and lose a lot of friends because of my sexual kinda things.

I don't picture myself as a normal kid. Everyone else knows stuff about alcohol and cars and partying and all that. I know nothing about any of it, i'm not a very social person since well when I was younger a game of Truth or Dare got a little overboard and I got teased for about 2-3 years straight and still get teased about it and that cause me to be very anti-social.

I put myself down a lot and so do others, the only positive reinforcement I get is from my girlfriend

I just want someone to suggest something that I can do or just something about any of which I said. I just don't want to be depressed anymore, I don't want to be in this horrible life. I don't know if I would kill myself but I never know what I do when certain things happen. One time I almost did which is when I went to the therapist. Someone please help
