Hey man, I hope you're doing alright.
I don't think all these replies are trying to put you down or attack you, I think they're trying to look out for you. I know I can't speak for all of them but I understand why they would say not to. In my experience, therapists take what you say weirdly in their heads and twist it to fit a narrative they've concocted. Whether you're passively or actively suicidal, they often jump to conclusions because they assume you'll take action. I'm really glad you have one that you trust, it's not something most people get to experience, having someone they can talk to about things like this. People here are attached to this site because of that, and they've been betrayed and taken from many times, the thought scares many. Me personally, I would rather reach out here because it's all people like me have, the safety mask of anonymity lets us speak our feelings, which we cant do with someone looking you in the eyes with their finger on speed dial.
I think they're worried you're gonna get sectioned or that they'll find this post and keep you under a microscope. It sounds to me like you've got a good head on your shoulders and you know perfectly well what you're doing. It seems like you've thought this through, you know yourself and your therapist the best. This is your life and it's in your hands, it's your right to make this decision, and if you believe it will help you, then pursue your peace and don't think twice. Don't listen to people if they're trashing you, they're insignificant in the grand scheme, live your life how you want. Hope your session goes well, love forever.
