Coping with Health Struggles and Feeling Trapped

I’m currently midway in the #not-girlboss-part-of-my-life. I’m coping with shitty jokes. My depression and health anxiety have never been worse, and I’m dealing with an undiagnosed vertigo disorder. My neurologist and ENT thought they had a answer with vestibular migraines but it doesn’t seem like that’s it. I feel so trapped, like the appointments are so few and far in between, and that nobody really wants to help me. Y’know that scene in the exorcist where the mom screams “oh everybody’s sorry” at the doctors? That’s where I’m at. I’m scared I’ll never get better. I see a therapist but I don’t think she’s right for me. And truthfully, I don’t know what I WANT because I don’t know what I NEED because I barely know what I HAVE! Just transitioned from pediatrician to adult psychiatrist and it’s like starting from square one. Please I need some hope, just some advice or a hug in the form of a text. I need to know I can get through this. Sorry for the long rant, but I need some friends <3 Does anybody have a similar journey? I don’t want to be alone.
