You may want to look at manpower most of us have issues keeping long term jobs. This may be a better options for work.

Look into your community center. My son and husband can use the gym and have karate 3x a week for $15 a month.

Life can suck....for months on end at times but you have to look at the very, small thing. Enjoy the hug that you actually feel nice about, the movie that you liked, go people watching ( you'll find the kindest acts done, it will restore your faith in humanity), a good song. Its easy to come up with things when in a good mood. I tend to color when in a bad mood. Its mind numbing but I'm sitting upright and it gives you something in the end.

I write a lot, I'll play the Sims in a bad mood I try to create the perfect family. I'm on an anti depressant (2 actually)

There's a bunch of free books for kindle app and some may be self help. Please call (or look online) your community health center, community action (will also help job search), Catholic charities, and dhhr for a list of charity therapists and psychiatrist. I use melitonin to sleep when needed and seroquel when things are bad for me.
