What should i do with my life?

[Bob]

I'm a sophomore in a community college. I don't do too well in school and on top of that i can't get a minimum wage job. I've applied for volunteering and internships and I have been rejected from both of those as well. When I apply for jobs I don't get a response and I'll even walk into the store to talk to the manager and they will say I lack job experience. When I apply for internships or volunteer opportunities they are always full.. I've applied to so many different places and I just don't know what to do. I have a 3.4 gpa but it looks like I'm going to fail a couple classes this semester which will really screw me over. I'm honestly really bored with life. I've tried so hard to get a job. A minimum wage job and I don't even qualify for that. I've never done drugs, not even marijuana. I don't drink and I don't even go to parties (mainly because i have no friends after highschool) I sit in my house almost 24 hours a day for almost my whole life. I'm getting so depressed that I'm starting to have suicidal thoughts that I can't do anything with my life. I've even went out of my way to create my own business on ebay, amazon, AdSense, etc and all those failed. I've had over 30 business ideas all failed. The only thing I can say is that I'm lucky to not be in debt and that I have literally 26 dollars in my bank account. I feel like I amount to nothing. I've gotten back up on my feet so many times after failing at everything but a human being can only handle so many failures. Should I just kill myself? All I just do is occupy space in this world and don't contribute anything to society. If not what should I do with my life. What other options do I have left. I'm considering military as my last resort. If I continue to sit here and do nothing I'll end myself. I want to live.
