Losing my Will and Struggle is getting Harder

I don't know if anyone will read this but I felt it is my last hope for help.
After losing my job in Dec 2011 for the 8th time after coming to the West Coast, I moved ahead with Part time jobs and starting my own bookkeeping service.
Now when I struggle to pay bills and keep the roof over my head {have lived in my car twice in the past 3 yrs)I am facing issues that are causing me to wonder why I even bother to be here.
I have even prayed and asked God to just take me from this earth, I cannot handle any more.
My car radiator is cracked, this is my main source of income, since I drive to client's offices for the bookkeeping services.
My work computer also just stopped working today, it has my clients files on it.

How much does a person have to struggle, cry, work hard to just make it daily?

I need prayer. Please.
Just need the help financially, need to feel some peace, feel some ease of depression and anger.

Too much is on me.
