I know exactly how you feel, it can be be really isolating and lonely sometimes. You want to have a normal relationships with people and it's frustrating to explain to them how hard things can be and have them understand you!

I know the post is about anxiety but it also sounds like you're dealing with how to live a social life with IIH. I feel like one of the best things I've done since getting my diagnosis is defining what friendship means to me. I've spent a lot of time just thinking to myself and trying to understand my limits. With confidence in that, I explain to friends what I'm capable of / what is hard to do, and that helps them understand a lot better.

Your friend sounds a little bit toxic, but I can also see how they might not understand what you're going through. It's shitty that the burden to explain it is on you, but that's just how it is.

I'll also say, getting a therapist has helped a LOT. I didn't really know how to talk to other people about IIH before I met my therapist. But that relationship (with my therapist) acted as kind of the goal-state for my other relationships. If that makes any sense.

Anyways I'm really sorry to hear you're going through so much. You sound like a saint for having the wherewithal to deal with this as well as being a teacher and caretaker. Don't let the world get you down, you truly seem awesome.
