I want to die, and it's because of my job

I wish I could just die. Not suicide, but natural causes or accident so that my wife and daughter could collect the life insurance. I feel like such a failure in life. I can't support my wife and daughter, because I can't keep a job. I have a master's degree, but my autism and depression make it very hard to keep a job. I take criticism too personally, question authority, get frustrated easily, complain a lot, and other things to get on the boss's bad side quickly. I am 32 years old, and in the 16 years that I have been working, I have gone through 28 different jobs, many lasting only a few months. I am defaulting on my student loans ($60,000+), am in collections from at least 5 different creditors, and was having my wages garnished until I lost my job.
My depression seemed to be better until a few weeks ago. I had to stop taking my Cymbalta because it costs too much. I have prescription coverage, but it is non-formulary, so it costs $60 a month. I am still taking my Prozac, which is about $17 a month. My wife and daughter are both sick a lot, so I have to choose between my meds or letting them see a doctor when needed.
Now my job is going downhill because of my depression. I wish I could go on disability, but I am physically able to work. It is just that my personality and my mental disorders make me a bad employee with a bad attitude. I have been on unemployment since September, and have applied for at least two jobs every week since. The only interview I got was the job I have now, and it has not worked out. Employers take one look at my resume, see the huge long list of previous jobs, and throw me in the trash. I apply for most jobs knowing I will never hear back, and that is frustrating. I can't work at Walmart or Kmart, because I failed their on-line personality tests. I am down to applying at fast food. I had hoped that my life at 32 would be somewhat improved over my life at 16, but that seems unlikely.
Thanks for listening. Sometimes it helps me just to vent.

 Wow its great that you love your family that much.You may feel lost,but they love you and that means everything.....I don.t mind that we have very low income,its killing me that hubby is leaving.I'm grieving as if he were dying....Please just seek as much support as possible so you can be with your family.We support you!!!!!!

My personal problems don't even stack up compared with your life hurdles badger..

You have so many great qualities about you that some people will never have if they live to be 100! You are obviously a family man, you have an education, you have energy, strength of character and a good understanding of who you are

So don't be so down on yourself badger - forget about the negative side - good grief we all have one of those..focus on the positive side..
