<human>: Give me the gist of the text in a nutshell

Recently I've been having problems at college; I'm about to get kicked out. 

Since the beginning of this year, my mother has relapsed into her depression and my father has become an alcoholic. My sister openly hates her job and my work ethic at college has effectively pissed off to pluto. 

I'm failing two out of the three subjects I took, and am most likely about to get kicked out. This prompted me looking at other colleges and then, apprenticeships. I found the RAF apprenticeship site and discovered several courses that I qualify for. As I've been told, the RAF is incredibly prestigious about experience and a guaranteed career. If you can get in, of course. 

I have the option to leave now and go flat out for the RAF, but if I don't get in then I will be left with practically no qualifications, no job and very quickly, no friends no life and nowhere to live. If I do get in, I'll be leaving my life behind and all my friends to go abroad and all over the place to install comms and shit.

I've been losing a grip on my life for the last three years, and I don't know what's going to happen in the next three months, but whatever does is probably not going to be fun. if I do get into the RAF, I'll have a long career that I'll most likely enjoy (eventually) that will get me high up qualifications and experience in the telecommunication and com-sat business.
<bot>: Life gone to shit, 50/50 chance that it'll either go further to shit or temporarily to shit then probably better.
