I am so sorry and I can relate. I don't take meds anymore though I am seeing a new specialist but when in a flare getting through the day is so hard. Sometimes I feel like I will lose my mind or not make it from the pain. This may sound odd but I try to self talk in a calm way that I have made it through bad times and I will again. Also do what I can to comfort myself which can be hard. I usually call my mom and talk, cry, vent. Sometimes my mom says you just need a good cry to help you feel better.
Question for you, you stated you have no insurance and so have to wait to change meds. Have you talked to your doctor about could he start it now if he has sample of the meds? Also you know if you don't have insurance some med companies if your doctor writes an rx will give you the med for free.
I hope you feel better.
