you probably didnt have a therapist that was a good fit for you. and there are a lot of different types of therapy. I empathize with you on your stuff, but you can't put the burden on someone else to do it. therapy takes at least 3 years of consistency to work. I am not you but it took me 13 years and countless therapists to find one that stuck and 4 years to heal from my life long abuse. And yes I do have disabilities similar to yours. Your experiences are unique to you and therefore important to you, as they should be, but they aren't unique when you zoom out from yourself.
It may feel like people are trying to erase you experience by sharing theirs, but they are just trying to relate to what you have been through, even if its not the same. I've been with my person for many years and he still does things that annoy me, but I don't force him to stop because I know that it is a signal that I need to figure out why it annoys me. I am no therapist, but am a person that understands and will help where I can so reach out if you want, but if you do, know that its your life and even with disabilities, you have to make it what you want and accept that people are not going to match perfectly. sit with yourself and ask yourself what you want most in this world, love or control. because based on what Ive seen you think that anything outside of how you live your life is bullshit and not worth having. BUT THAT IS A CHOICE.
It seems like you want life to be easy, but you are posting this in a r/ where people are trying to overcome in their struggle, not sit in it, which is valuable, but at some point you have to stand up and go fuck this and go for the goals that you want and that is your CHOICE. Ultimately I think that is what everyone is trying to say and show you. And instead of feeling supported and seen you are defensive. We can all clearly see that you are in pain, feel free to reach out if you want, but know that I will hold you accountable for the space that you hold yourself to.
and if you dont reach out, please read
