If we're talking disorders, then I'd say generally if the stuff you do/think because of the disorder disrupts your life on multiple levels, then that behavior/thinking pattern is too much.
But yeah, not a professional, so idk, maybe try asking your therapists? xD

To me it seems like a rather extreme reaction, to be completely honest Because of your bad experienced with people you assume literally everyone will hurt you one way or another. I totally understand where you're coming from, but... That's pretty extreme But you choose your own comfort and that's okay.

I don't have agoraphobia but I often catch myself making excuses for not going out to the store, or interact with the cashier, ask for anything, such "simple"daily thing "normal" people don't have issues with. I used to push it all away on Ash. Now that we don't live together it's evident that I am capable of actually being out there and doing fine, it just take some getting used to this ish. But those small interactions, going out on my own, taking cre of my own ass, it all gives me a sense of independence and restores my self esteem. I don't feel like a complete failure if I can go to the store and buy myself something to eat/drink so I don't die XD
I think in general phobias are really hard to battle and I'm not sure it's possible to win with them. However one thing I know is that no change can be forced. If you are not ready or you just don't want to change, you won't. Is there anyone who forces you, though?
I'm sure there are people who got their phobias under control to the point they don't have such intense reactions. But I have no idea how one would achieve it. Perhaps there's a specific type of therapy devoted to that, but I'm an ignorant peasant

I can understand and respect that you don't want to change. It's what you know and it feels safe for you. I think that's a natural reaction, from that point of view. That said, I do think it would be somewhat easier for you if you considered some changes. But it's up to you and it's none of anyone's business.

I'm sorry people seem to ommit you and decide for you. That's not okay

Oh yeah, it's actually very easy to go from bullied to bully. I actually had a short episode in my life... I'm not proud of it. So it is something you definitely can be proud of
And lmfao, being a social butterfly and extrovert is not "normal", people on the whole globe are different. Being different is normal, lol, leave me alone XD

I don't understand why she felt bad for you, did you at any point sound like you're sad about it?
You do you then
I don't have much interest in going out, but sometimes it's nice to meet with people. For a certain amount of time. I get tired of people pretty darn quick, I get so drained and sleepy...
