<human>: Could you distill the essence of the text into 1-3 sentences?

Well, here goes:

21 yr old guy who studies computer science. My life is really actually(!) near perfect:

I have an awesome flat (I just have to roll out of bed and I'm at the institute. Rent is damn affordable and cool roommates), look decent, decent sporty (Hitting the gym soon since it's five minutes from here), did pretty decent in university until last term. Enough friends and social skills available (As far as I can judge).

But: This term was suddenly hell. 

Fast forward, Finals are up. I failed 2/2 pretty hard. Tomorrow is the third one and I'm not sure how that one will go. Have the chance of a second try in all three in about a month, but not sure if I'm gonna do that in all of them.

I know exactly I overdid it with everything I wanted to accomplish this term. But even though I tried to get a little more steady (e.g. quitted Japanese, was doing it for fun), I'm fucking up even more. And it's not like that all that stuff is too hard. It was just a mixture of lack of time/can't think straight atm/motivation problem.

And if next term is the same as this one I'd rather go to hell.

I know a restart can't really help, cause I'll do the same over and over again (Be lazy, take it casual). I know you start life now and not tomorrow. But fuck I can't. All my aims are rising to my head and it's exploding. I don't want to fail. In university, in sports, in life. Anything. 

How can I get my life sorted out before it affects my social enviroment too much? As an example: 
I stayed at home last night cause I was ashamed of myself instead of going to a buddy to watch the game with a few beers. I know this is really no big deal, but my behaviour is kind of alarming to myself.
<bot>: Fucking up my life atm little by little and asking how I can sort things out before I get my personal life being affected by it too much
