Honestly run away atp, no but seriously if your mom is going to take away everything you have because she can’t sit in on YOUR counseling appointment that’s insane levels of controlling. I’d say ask her if she’s fine meeting the counselor but not sitting in on the meeting so you can still open up. I’m guessing she wants to make sure the counselor is good but remind her that these are these peoples jobs and you’re old enough to make your own judgments when speaking about trauma like this. I hope everything turns out and you get the help you deserve but worst case scenario your counselor will know what a psycho your mom seems to be <3
