I'm sorry that you're feeling this way. I hope things get better for you soon.
I do understand the pressure regarding the job. I was that way a while ago - we were having severe financial problems because of some really poor spending habits on my end, and I had trouble finding a job. Yet at the same time I was having trouble even functioning enough to take care of daily life...let alone spend 40-60 hours a week working. It's a catch 22 kind of thing.
I'm sorry. We're here for you. And if it helps boost your confidence a bit - I think you will make an EXCELLENT therapist simply because you know what it's like. Empathy is a wonderful thing that many therapists lack.
Good luck.
