Still homeless

Since my last post, a fair amount has happened. I initially got a job as a line cook, but could only handle it for a week. Seems that my walk across the country left me with back, leg and feet issues. It's extremely painful to stand on my feet for more than a few hours. I blame my crappy diet on the walk.
After 4 weeks my mom bought me a car, and that was great, but it has all kinds of issues. The transmission sticks going into second and the back breaks are bad. Mom said it was a sign from God that she should buy this car. I asked her to test drive it but she said she doesn't know anything about cars, so what's the point. It drives okay, but I know that in the next year, I will have to cough up a few grand just to get it right. Had she just given me the 2 grand, I could found something much better, and had money left over. But i guess it's a control thing. Beggars can't be choosers right.
I also got a job at 711 but that only lasted a week. Same problem, back and feet.
So now, almost 2 months in, I'm only better off because of the car. I can sleep where ever allows overnight parking, IE Walmart. I've outfitted the windows with removable foam board for a little privacy. My only issue with car camping is that I have to plan my bathroom breaks. I have a bottle, but I don't like having to use it.
I'm now applying for delivery driver jobs and call center ones. Sit down jobs mostly. I am well past the point where I need to have a place and a steady income.
I'm still very fuckin angry at my shit family. I understand my mom's motivation with getting me the car. She has also donated several hundred bucks to my wayward position. But she does so, because is so fuckin ocd, and offering her guest room means fucking with here well ordered life. Still pisses me off though. My siblings, well they know I'm at Rock bottom, but I guess are to busy to care. They are praying for me. I just doing so, replaces the need to actually help.
I think about suicide at least a few times a week. I feel as if I have no way out. No hope. But then I remind myself that I don't believe in suicide. I'm just at the lowest point I can remember. Eating tuna on the side of the road in Mississippi was better than this. Hah!
I'm giving it till Friday, whereupon if I don't get a decent job, I'm moving to Panama city. Lots of jobs there, and I won't have to be constantly reminded that my family are a perfect bunch of douchebags.
