AIO at my mom for consistently bringing people to my therapy sessions when I’ve made it clear I’m uncomfortable with it?

There’s an old proverb that states “Don’t attribute that to malice with what can be attributed to stupidity”. I hate to call my mom stupid, but at the very least, she doesn’t understand boundaries and why confidentiality is important.

Last year, I (16M, but 15 when this all started) began therapy with a LGBTQ+ and ADHD therapist after being kicked off a travel hockey team for coming out. I was suffering from depression that made it impossible for me to get any sort of meaningful schoolwork done, which especially screwed me over since my mom also refused to put me on my much-needed Adderall prescription. Also, my hockey academy relies on a homeschool service to school its student athletes, so all of this combined meant I was failing school miserably.

Right after I got kicked off my team, my mom brought me to my therapist for the first time, and over the last 6-7 months, the therapy has transformed my life for the better.

The only issue is that my mom won’t stop bringing people with me to my therapy sessions. They don’t go into the office, and aren’t involved in the sessions by any means, but it still pisses me off quite a bit that my mom doesn’t understand why I’m not fond of this.

For the first month or so of therapy, Mom understood I needed time and space, so she didn’t bring anyone along, and always made sure to spoil me afterwards at the local coffee shop and record store.

But after the first month, things started small, like having to bring my sister along with her to pick me up, which I can understand since she has 2 other kids. But unfortunately it has spiraled since then. She has routinely brought neighbors with us, and at one point it was the extended family of our neighbors. And not just to pick ups, but drop offs as well.

I think the issue boils down to mom not understanding why you don’t out gay people either, since she has unintentionally outed me to my Dad, Aunt, Uncle, and cousin at one point or another. She has also outed my sister (13F) as a lesbian to me, which while I’m not in any position to judge, still not ok. I think she views gayness as a matter of fact and not an emotionally charged thing that many people hide, for fear of being judged. I kind of find it supportive in an odd way, since she isn’t judging me or anyone else for that matter, but the lack of social awareness is a bit infuriating to say the least.

Am I overreacting or should I give up and accept that she’s going to tell the whole world I’m gay.
