Hi I took 1 10mg amitrityline 2 weeks ago and haven't felt the same since. I don't feel excited, or motivated, or happy. I have hardly any reaction to looking at things I really love. I feel hopeless and like I can't cope. I have insomnia every night. Huge anxiety. Can you get PSSD from 1 tablet? I wish I never took it. I know I sound crazy now and everyone around me thinks so, when before all this I was doing well and positive and ready to enjoy life and games and connect with people. Now I'm behaving so terribly but I'm so scared and can't feel the same. I can't even be loving towards my family. I'm acting like a person I would never want to talk to.
