Hi there,
Have you ever seen a therapist or pdoc about this depression?
If you haven't perhaps they can help you and you may not have to go to the hospital to stay, sometimes it is about 4 to 10 days for observation and mood stabilization with meds. it does get better, slowly, but it will and if you work along with the professionals it may help speed up recovery.
Just my 2 cents, meanwhile feel free to come and talk to the others, sometimes I find it better than therapy, and you don't have to dish out the cash Please do not misunderstand me, it isn't meant to replace therapy, etc. but the people here are great to talk to.
Please take care
