Complete loss of Interest in Life.

I'm leaving this message asking for help. It's been almost two months and since then I've begun to notice a lack in any emotions whatsoever. From what I gathered off of the Internet this isn't much of a farfetched concept since many others seem to experience the same type of problem. In order to give you a better grasp of what I'm going through I will explain to you my situation. A few years ago I discovered that I'm suffering from a sever inferiority complex; Basically very very low self-esteem. This begat problem after problem until I was so afraid to try anything in fear of not being good enough, it just rendered me inactive. As you know its just a cycle that feeds its own fire. The anger that formed from not trying fuels my inhibitions. This is problematic enough for me and since I am trying to go into a field of art seeing others work I always feel pathetic in comparison. Of course this is just one example although it is primarily the reason why I tend to recede so often throughout the course of my week.This persisted, so bad in fact it cost me dearly. I lost my girlfriend, majority of my friends, and it caused me a tremendous amount of emotional torment. But I carried onward, doing my absolute best to regroup everything to piece my life back together. A bad decision left me in another rut going to a school I hadn't really picked and a roommate who betrayed me. So being as fed up as I was I found my second wind. I wanted to do things my own way, with a new job in hand! Placing together my portfolio was hard but defiantly rewarding. Having two colleges in mind I decided to apply for both, I was accepted to one of them. It was a milestone for me and most certainly a great goal achieved.My job turned into the center of my problems, turned out my coworkers were all drug abusers. It was a local electronics store right in the middle of the city; People there were abusive thieves who constantly badgered me. I even went above and beyond to help the place out until I was laid off after the holidays. I went jobless for two months and during which I was forced to help out my parentals. You see they had placed a large investment to place an indoor soccer facility and the gimmick is that its the first of its kind in the entire area. Problem was poor management as everything turned for the worst. All of the partners, including my father ran out of funding and since our house is up on the line the stress just hit everyone. Now I mention this because for the past two and half months I was actually helping with construction of the field, which was one of the worst jobs I've ever had.I now work at a local coffee shop three blocks away from my house, since my car always breaks down this is quite a blessing for me. Though now I'm having trouble finding any enjoyment in my life. I have no friends where I live which forces me to use the Internet for any conversation and even that is extremely limited. My bad mood swings, including my fears of dealing have caused me to lose nearly all of my contacts. Even now my conversations are dry and mainly consist of me rambling on about my problems, if they don't people eventually up losing interest in talking to me. I can't find any excitement that I'm going back to school, or any interest for my hobbies. I no longer enjoy anything. It feels like the world is floating around me and no matter how hard I try to grasp it...I just cannot. I don't know what to do, I feel utterly helpless and each day is becoming harder to cope with this. People have suggested I seek professional help but I cannot afford it nor do I have health insurance of any kind. I no longer experience dreams of any kind, I've slept horrendously ever since I came back home. If anyone has any advice or help from personal experience please let me know. I greatly appreciate you taking the time to read my outcry, thank you in advance.
