you have done very well in finding a job and solving one problem, regarding fibromyalgia and migrane i am sure ur on medications. regarding depression have u seen a doctor yet? or are u on any medications?. solve one thing at a time, try to find out from local banks if you can get a loan, or talk to close family and friends. talking to other people makes u feel slightly better and also they might come up with some ideas to solve your problems.
All the best, we are with u in ur times of hardship
