Feeling hopelessly desperate

Hey there, so I've been dealing with anxiety since forever, it's kind of like my constant companion. Then in 2020, I got diagnosed with CPTSD and tried EMDR and hypnosis, but nothing really stuck. After that, the panic attacks became super intense-more like seizures or fits.

I've taken pretty much every antidepressant out there: Fluoxetine, Mirtazapine, Venlafaxine, Quetiapine...none of them helped. Now I'm on Sertraline adn Diazepam for anxiety, Losartan because my cholesterol is high, plus I take ibuprofen and paracetamol to deal wiht the physical pain from a hiatus hernia.

About seven weeks ago, something weird happened-I got really sick with what sounded like some kind of infection. Ever since then, I've had chest pain and a racing heart. Sometimes I just fall down in the street and can't figure out why. My GP said there's nothing else they can do for me, which leaves me feeling pretty lost.

So yeah, any advice or suggestions would be super helpful!
