Those symptoms do not sound "high functioning" to me.
Limited focus, meltdowns, emotional disconnects, and distractions of everyday life need to be managed.
My anxiety and meltdowns I have experienced are almost exclusively JW cult exit related. The other day it took several hours before I felt like going out for the day. Couple of times I just had to lay down. Sometimes a dark room can help get one back on track.
My weakness is people that genuinely act terrible in front of me.
I used to just ignore them and let it go. After being taken advantage of for so many years in WT, I refuse to let people screw with me. This tends to get me into hot water...
