Post drug use depression

Patient: I’vebeen using drugs for 10 years. When I found out I had been accepted into uni I decided it was time to quit it all. It’s been 6 weeks since I last had anything. At the time of quitting I was smoking cannabis daily, using heroin (not IV) once every couple of days, other things like Meth and MDMA every other weekend, and drinking alcohol quite regularly. I am physically feeling better but feel like I am slipping deeper into a manic depression. I’m told it gets better, take it day by day, but everyday it feels worse. I’ve been trying to exercise regularly, my diet has always been pretty good.I am at witts end, and it’s just getting too hard to focus on my studies, or any other obligations through out my day to day activities. What can I do?

Symptoms: depression
