Recently diagnosed with FND tw csa and suicide attempt

I had tardive dyskinesia (involuntary movements) caused by long-term use of antipsychotics for 2 and a half years before developing fnd for the second time. The first time I had pain in my vagina from csa for 5 years before a gynaecologist diagnosed me. This time I developed it after coming off olanzapine (the possible cause of my tardive dyskinesia apart from lithium) too quickly. I had severe involuntary movements and was treated as a malingerer by my psychologist and a horrible emergency doctor. Now the movements have mostly stopped but I am bent over, tip to the side when sitting, have a severe loss of balance and can barely walk 50m without falling over, so I am now using a wheelchair for long distances. The more I walk the lower I get to the ground.

My psychiatrist insists it's fnd but my neurologist insists it's not and it's medication-induced extrapyramidal side effects. I'm having schema therapy for it and I've had years of emdr which has helped immensely over the years but I still feel I have dissociated/suppressed memories of severe csa according to my sister who was abused with me and it's absolutely soul-crushing. I don't see how just talking about things is going to help and I feel like I'm climbing up a mountain. I attempted suicide over this and was not taken seriously by the hospital. I've had so much trauma across my life time and I just can't seem to catch a break.
