Where do you live sarahsmith?
When I was unemployed I had to live in a 1 bedroom granny flat in the backyard of some drug dealer's house.
There was no security. Anyone could walk into his backyard. The locks on the granny flat were easy to pick.
I got my stuff stolen several times. Even my TV. I'm pretty sure it was the drug dealer or one of his friends. The cops did nothing but write down some notes.
Like you I was scared to get a full time job. But I took a leap of faith and I got one.
After that, I could afford to live in a cleaner and safer house in a neighbourhood with a much lower crime rate.
I moved into a more secure apartment in a low crime neighbourhood until the bank approved my mortgage for a house in the same neighbourhood.
Anyway this thread is about you, not me. What I'm saying is that if you take the plunge and get a job you may find that having a job isn't so bad and you may be able to move into a place where people don't steal your stuff.
If you can't handle the job, just quit. You'll be no worse off after quitting than you are now.
At least you'll know for certain whether or not you can do it.
