Hi Serendipity22. Yes, I was prescribed Amitryptline about 4 years ago for anxiety which was keeping me awake at night due to a family problem. I also experienced panic attacks in busy places like supermarkets. Only 10mg, which I found was enough to help me sleep. During covid I had more problems so was told to increase it to 20mg.
It works fine for me. I sleep well most nights and am feeling calmer. It also helps a bit with pain (bad back), and my speech problems.
I don't know if I am addicted to it, and because I am 84 I figure that I don't really care if I am. I will take it for the rest of my life, hopefully. It seems to suit me well.
I imagine the menopause might play a part in your continuing anxiety, but I'm not sure. Best wishes and I hope you feel better very soon.
