Always depressedI need some insight on what I should do about my depression. I've been depressed most of my li?

I recently went into a deep depression and started meds. They worked for awhile and i started psychotherapy but the depression began to get worse (even with med adjustments and additions) i was weaned off the meds and i stopped therapy. I dont think its working. And i can pinpoint most of the reasons why i am sad all the time right now in my life and I am working towards getting to the root of the problem so that i can be happier but it is so hard. I have a stressful job and I have been trying to quit it but i have money issues...i'm trying to go back to school, its alot of things. i dont know how to stay positive but for only a short amount of time. I am always sad and I don't know what else to do about it. I've been in and out of therapy since i was 16.
