My psychiatrist won’t address my anxiety

Hello need advice on what to do, my Dr won’t address my anxiety besides telling me to take more hydroxide and up and downs my Lamotrigen. She says every appointment “we’ll see how it is next time” or “let’s see after this specialist” or even if a specialists advice she doesn’t hear it and prescribes me something completely different. This has been going on for years and I’m don’t with her. Plus she’s booked out for months and she keeps being out of the office for weeks at a time when I need to see her the most. I have to have a referral from her to see another doctor but again she’s out of the office until the end of August! It’s making my days miserable and I’m waking up at night and instantly am in a panic attack or I’m having sever stress dreams when they’re so emotional it messes my whole day up. I have ptsd and have to sleep with my back against the wall and even then I still feel like somebody’s creeping up on me. I don’t know what to do they said if I see a consult dr or whatever they can’t change my meds and just take them away. Now they said stop the hydroxyzine and my methylphenidate (Ritalin) I also have a TBI and have frontal lobe damage and without that I can’t get one task done. I’ve been making solid steps to improve my life but I’m still miserable, it’s making my days miserable and nobody is listening to me. I also deal with severe pain from 4 herniated discs along with other severe health/pain issues. I’m exhausted, miserable and feels like there’s nothing I can do about it.
