I Want to Feel Nothing...

I've dealt with depression and anxiety for years. I've had a bad case of both this weekend. I'm so exhausted. Drained. Tired of crying. I want to take something so I can't feel eny emotions. Maybe I can relax. The doc has me on Cymbalta, but that hasn't worked well lately. The doc took me off Ativan when i got pregnant which always calmed me down. I need something now. How to go through another day alone with my thoughts? Terrifying.
