Don't be sorry, I'm here to listen and help if I can.
Keep in mind I'm not a real therapist but it seems to me like your issue could be a lack of motivation and self esteem. Essentially part of your mind is telling you "hey you worthless loser, since you're not doing anything anyway, why doncha do everyone a favor and die?". Don't listen to it. Embrace life to the fullest!
Do you do have any hobbies, play sports, stuff like that? I'd suggest you start doing those things. Get outside in the sun, go hiking, pick up a paintbrush, keep a journal, etc. etc.
And even if you don't like talking with people, just hang around and listen to them talk. Your mind can become stagnant if it's stuck with just itself for company for too long.
Lastly, don't ignore those thoughts. Write them down and try to understand the reason behind them. And I'd suggest going to an actual therapist, for all I know I'm doing more harm than good here...
