I need help.

I'm 15 and I'm a guy. I dated this girl for 8 months and it was the happiest time of my life. I know I'm young but 8 months is a long time to be with someone when you're a teenager. I really did love her, and I still do but I'm torn between the fact that she wants to move on out of no where and I'm sitting here living in the past long as I can :/ I've been heartbroken before but idk this time is different. I thought everything was going great, she acted like she was happy all the time and I really thought she was. Just idk we've been broken up for a few weeks now and I still feel horrible. I mean a few weeks isn't really that long but still.
But now that I've had mah pity party I'll talk about what happened the day we broke up until now :P I was coming home from the camp that I spent the weekend with her nd her family. The car ride home, she seemed kind of upset, sad and annoyed and I couldn't understand it. The weekend was fun and we both had a good time. well when I finally got home we were talking. She said that her and her mom were talking, and that she thought that we need to take a break because we were too dependent on one-another for happiness, which I could understand how that was unhealthy and all that so I agreed when she said it was just a break. A few weeks later we were talking about the break. She said that she wanted and I didn't really understand it.. She said that I always made her sad because I was constantly depressed which made her sad, because she couldn't make me happy.. Even though she did. And that's were the problem started. I'll admit that I was constantly depressed, but I didn't enjoy it any more than she did.. I don't even know why I was depressed.. I just want to know how to know how I can stop this depression.. I don't really have any way to cope so it just builds. idk I'm a really shy kind of person too. So we didn't really go out and do stuff. I just want to change these things about me.. I know that it's probably to late to get back with her. But if I ever find someone else again then I need to know how to correct my faults.. I know that if she would give me a second chance though, I'd change everything and do it all differently. Idk I'm trying to be really mature about this though because I know that it's what she wants and I don't want to keep her sad but at the same time I don't want to have any more pain.. I've had a lot but idk how much more I can take. I know all that should matter to me is for her to be happy but I feel like that towards everyone. I always have takin the blame. When is it my turn though? To be innocent for once. I mean I know that eventually I'll deserve some happiness.

Well that's how I feel right now lol. I know that I'm not hurting as bad as others are just. Are there any mistakes that you can identify and make appearant to me? I don't want to hurt anyone else ever again..

Welcome to PC!

It's good that you don't want to hurt anyone...the word "again" is probably a bit unrealistic...as there are things we will do that without the actual intention will hurt people...but I get the idea that you want to be as healthy as you can be...

She brought up depression, so I would let your parents know that you would like to talk to a therapist...you can say its so you can work through x and y issues unless they already see the signs of depression too...I don't think its any mistakes here I can identify for you...I think its just a matter of working with someone professionally...ok...I know I wish I had at your age...
