I've been in and out of it a few times. Basically the only use I got out of it was for bereavement everything else was basically pointless.
One therapist basically called me an incel (and would have it was common parlance at the time) and said it wasn't normal for me to have never had a gf at 23 and said my life would keep getting worse the older I got. Made me feel awful.
Her suggestions were to google "how to make friends" and talk to my mother more (who was the only person I talked to anyway).
