whatever you did/feel guilty about is probably not as big of a deal as you think it is...i'm not saying it's not a big deal, i'm just saying it's not worth killing yourself over...
think about it for a second...there is so much more to life than what people make important...we place education and good grades and a good career and lots of money and a giant flat screen tv and a nice car at the top of the list...but none of that is important...by the same logic, our mistakes aren't as important either...we ALL MAKE MISTAKES...we're human, that's what we do...to some extent, even most criminals in jail serving life sentences or sentenced to death for murder have simply made a GIANT but stupid mistake...they made the mistake of killing somebody, probably over something that wasn't worth it...
and i can tell you that whatever you did that you don't want to face cannot be as bad as what you are planning to do...there's a saying - "suicide is a permanent solution to a temporary problem" ...try and place what you are doing next to what you have done...no way in hell it's worth killing yourself over...
also, think about the future...all things you won't do/see/experience...all the people you won't meet...all the food you won't taste?!
even if you did something that is going to alienate you from everybody important to you in your life, screw it...let that happen...those who truly do care about you will forgive you...and those who don't forgive you don't really matter...and, take it as an opportunity to start over, whether or not that is what you want...there's some beauty in being able to start over...that's always an option...you can always make new friends, meet new people, get a new job, move to a different city/state/country...you can make some sort of a living just about anywhere - enough to survive at least - even with the most minimal education...
please, tell somebody online what you are facing...feel free to PM me if you wish...i won't judge...and i'll do my best to understand...or, there's many other people on here who are good for that...we've seen it all, done it all, heard it all...okay?
if you don't want to die, then don't kill yourself...
