Help needed ……………. ..

I was on blast and cruise for many years unfortunately I had to come off due to terrible life circumstances and never run a pct . Test is now 10nmol . My anxiety and depression is extreme.
I feel like my body is stuck in flight or fight mode .
My penis seems to shrivel up all the time . Would restarting trt help somewhat ? I’m worried about starting it and it not having any benefit . Thank you
