Trying to find work

Since the summer of 1998 until last March, I have not had a regular job for probably all of five months. I lived with a single parent so if I wanted to have any sort of fun or wanted to buy something, I had to earn the money myself. I’ve done a various number of jobs but I’ve always had work. The only two times when I wasn’t working were two months when I went to visit family in Europe back in 2006 and the first two months when I moved to Vancouver in 2007. From the end of March until Now (so going on three months), I have been trying to find work with absolutely zero success. In fact, in all that time, I’ve had one phone interview. The only other closet thing I had in regards to a position was having a company e-mailing me to ask me where I was located (they never responded afterwards). I have been looking regularly for work in my field with almost zero responses. What makes it worse is that a lot of the companies and positions I have applied for update their job sites to give you an idea on the status of your application. So, seeing me being rejected for a position I felt that I was qualified for without even a simple phone interview is extremely frustrating. I really want to work but the field I am looking at appears to not want me and I’m not sure why. I’ve been working in the video game industry for four years; I have four years of customer service experience but I just can’t seem to find another job. I am knowledgeable about video games and sports but my opportunities are slowly dwindling. But what is really funn is that I am able to apply to 5-10 different jobs a week that I feel I could do but according to those companies, I am not what they are looking for. And now it’s beginning to damage me emotionally and physically. Since losing my job, I’ve had to relocate twice. I am in a city I absolutely hate and in a living situation I can’t stand. I have problems sleeping and I have begun to gain weight at a steady rate that I just can’t seem to stop. I am used to challenges but this is by far the biggest one I’ve had to deal with and I am clearly losing it. I can’t even turn to family because being around them is actually more detrimental to my health and well-being. My family were part of the reason why I relocated but they have been of no help, and that includes being supportive. I just want to work and being unable to find a job is making me both sad and angry. I don’t know what more to do since everything that I have tried in the last three months has amounted to nothing. I’m running out of ideas on what to do. I thought by moving the change in scenery would help, but that hasn't been the case. I’ve tried to cater my resume and cover letter for each job so that I’m not simply mass-applying, but that too hasn’t helped. I never thought trying to find a job after being laid off from another would be this hard. Clearly, I am suffering from some sort of state of depression. I am finding it hard to go on and I'm not sure what more I can do. I just want to be working and doing what I am capable of doing. I need to get out of here before I end up hurting myself even more so. I wish I knew what I needed to do because I'd do it in a heartbeat.
