Lorazepam
"I suffer from obsessive compulsive disorder, anxiety, post traumatic stress disorder and depression. It has worked wonders when I start to suffer. I take 1 mg in the morning and I feel like my old self again. However, I'm starting to wonder if it is causing some of my depression. Once the medicine wears off my mood crashes. I get very emotional, anxiety creeps up, agitated, and very depressed. I pop another one and my mood stabilizes.
Another thing, it is very habit forming so don't stop taking it abruptly. Consult your doctor first for a plan."
