I have trouble showing affection to my mom and I have this condition too. But I've literally never seen anyone else say they have this problem with hugging before too. What's it like for you? Maybe we could help each other understand it, no one else seems to, and I don't either lol but I can tell you what it's like for me.

As for where to get help, you can try a therapist and try Exposure therapy or CBT. Both help me a little bit. You could also get some anti-anxiety meds if you're comfortable with that.

I've done a bit of Somatic Experiencing and it seems like it could be really helpful if I stuck to it.

My teachers picked on me too. That's not a good characteristic of a teacher.
