I found a "fix" for the woozy part several years back. I used to think it was panic attacks, because I do get those, so in would try to relax and lower heart rate and all that I do with panic attacks. Turns out it was a vasovagal response, not panic, so it's low, not high blood pressure. So all I was doing just made it way worse. It's a reaction meant to help reduce blood loss after major wounds, but I happened to one day cut my finger pretty bad and happened to have a smart watch on and as I was getting dizzy, it warned me that my heart rate was dangerously low. So I read about the vasovagal reaction and that autistic people can sometimes have an exaggerated one. Instead, I immediately start hyping myself up and if I'm not dizzy yet, I get up and jump up and down and get the blood flowing. Anything to get the blood pressure back up. I still sometimes still get some ringing in the ears and cold sweat, but I haven't passed out since then.
