You are not going to lose it or go crazy! since I have been put on the Propanol 80mg., I feel so much better and my tremor is gone and I sleep better! I had RAI treatment 3 weeks ago but am still in hyper-stage! I felt like you do 3months ago! It will get better! But you should not beat yourself up because you can’t be superwoman now! How long have you been on the meds. and what dosage? Take each day as it comes and don’t wrack your brain cause your not feeling your best! 3 months ago I thought, I don’t wanna live like this forever! But it did get better and I know I’ll have more hard times coming but I’ll be ready for them! Take it a little easier on yourself! It’s o.k. not to feel the greatest and always the best! You’ll be on top again! Take care of yourself and allow yourself to NOT be the best ALL the time!
