Purplekitty *hugs*.... I know what it's like when your bad health just makes you feel depressed, and you can't do anything about it....well like the other ladies suggested give yourself time, write a journal, go through the medication, believe it will work, the doctors will help you out.
For now treat yourself with your favorite music, good and healthy food ,visit or call friends, read, watch your favorite TVshow, manicure, sleep a lot....it WILL all get better soon. Hang in there.
