You may need a different med or med combo for sever depression. Meds help but they aren't the cure all, you need to take steps to get better, healthy food, exercise, sleep, clean and organize your living environment, etc...

Meds didn't seem all that successful in lifting my depression. Since I started changing behaviors and habits for the better it has made all the difference. Start out slow with one behavior, when that is going well then add another. It really will help.
