I had good results for my perpetual anxiety and panic attacks (GAD diagnosis, now understood to be PTSD/CPTSD)
with low doses of Effexor XR.
I have been on it several times over my lifetime. Longest span was 7 years. Meds can be useful tools for helping us through the hardest stuff. There are so many options out there these days, there is no reason to suffer. Sometimes it takes a while to find the right drug or combo that works the way you want without undesired side effects, and sometimes adjustments might need to be made to doses, etc, but the difference for some people is like night and day, or literally and actually the difference between life and death. Don't give up!
