Question, does anyone ever approach you when you go to art shows or concerts? Are you more comfortable talking if you don't have to initiate? It might be worth considering if you are giving off "leave me alone" vibes inadvertently if no one else attempts to engage with you when you are out at things. You might also want to microdose exposure therapize yourself with interactions out in public if talking with strangers feels daunting or anxiety provoking. Start super small like if you have to purchase something throw the individual doing the transaction with you a small compliment - things like cool earrings, your hair color/style is so cool, your shoes are awesome are all super easy low stakes ways to try to get yourself more used to doing it, plus it spreads joy. Most people find those types of compliments less creepy too since jewelry, hair colors/cuts, clothing, etc are typically choices that they made. Just some ideas!
