Any point to Physical Therapy?

So to sum up: Lots of endo symptoms, been on the wait list for nearly 3 years now. I went private last year at the rec of a GP to see if I could get any tests done that could bump me up the waiting list. Private gyno attempted a tv ultrasound but couldn't even insert it from how much pain I was in and sent me to physio for vaginismus. Not surprising because I get a lot of unprompted vaginal spasms too and they hurt like hell. Been in physio since September and it hasn't been going well. I'm not emotionally distressed by examinations at all, the pain level's just too bad. My physio suggested starting by just placing the smallest dilator at the vaginal entrance, which I was happy to do, but even that was painful and would cause spasms up the vaginal canal so bad I'd be on the floor or have trouble moving for the rest of the day even on painkillers. She attempted a physical exam with half a finger and I couldn't sit down properly for a week. Can't apply lidocaine cream because my finger can't fit into the vestibule and I attempted mixing it with water and spraying it on a GP's advice which might have worked? But the same vaginal spasms regardless. I also get bad cramps afterwards, but even on birth control that works well I bleed whenever I'm stressed/in pain enough, so I don't know if that's something specific to this problem or that would just happen with that level of pain in any body part. I'm trying another antidepressant as a nerve pain manager, but my physio's made it pretty clear I'm close to being dropped from pt since everything suggested has either done nothing or made things worse in this regard, which sucks. I could just be being sensitive but it feels like they decide for you that you're just scared of penetration and when that isn't the case they just shrug at you. I am wondering how much of an effect endo might be having on these symptoms though. If that's the case, is it even a good idea to keep trying physio at this point? I know it can help some people with endo symptoms, but on the other hand I'm wondering in my case if I would see better results if I could deal with potential endo first. On the other OTHER hand I haven't seen anything similar here or on vaginismus resources, so I'm kind of lost. Also I've been lowkey medically banned/Strongly Discouraged from masturbating because that hurts too and I AM giving permission to giggle at that because God knows I need a laugh right now.
