<human>: Hello. I apologise in advance for my jumbled up thoughts, I am literally all over the place. 

I am heading to college soon and I have been under a hell lot of stress because of the same, coupled with an awful grade in physics and an extremely gruelling relationship. 

We've been friends since I was 3 and he was almost 5. Our parents are friends, same school, same hobbies, same friends, blah blah blah. We've been together for just a little under a year, a while before he left for college. We both have an array of issues. I have/had severe depression, as well GAD & PTSD to go with it. He's bipolar and hands down, the most impulsive person I have come across. Neither of us ever try to excuse our behaviours by blaming it on our disorders,  but discounting their impact would be stupid. 

There is no concrete problem here and that's the worst part. We're both defensive and possessive. We are both painfully, excruciatingly possessive and we have been able to deal with the problems or caused and we are also working on it slowly.  What I'm not able to shake off is his insecurity which is linked to any success I have, no matter how minor. I brought home a trophy from a biology  symposium a few months ago and he completely flipped out, saying he felt like a dumbass and felt so inferior and that all he ever succeeded at was sports. This is not true. He did well academically and is in a very good program currently. 
He also keeps reminding me how inadequate he feels because I'm graduating at 16. This is so shitty and I know everybody will say that this is a total deal breaker and that I shouldn't stand for it. But I cannot let him go. I want to make this work. I know he has issues.  I know they are worth working through. I just want to know if it's possible.

Can you condense the text into three sentences or less?
<bot>: Boyfriend and I are equally manically possessive. He feels inferior because I'm graduating school "way too early".
