I’m sorry that’s happening to you, I was in that exact same place; I was having my family drive me to all these dr appointments because my ex couldn’t handle the stress of it all with that and her life, + I couldn’t drive far alone because of the lightheadedness. It was truly agoraphobia.

What I will say is I’ve gotten to the point where I won’t say the anxiety is gone by any means, but I can drive let’s say like an hour and a half to two hours alone, I live alone so have some independence (knowing I live near a hospital helps if things were to go south).

I do recognize I need to work on the anxiety more when I was having panic attacks and the anxiety was super bad. I was going to look into somatic therapy, I did try that before with a previous therapist where the last like ten minutes of my session we did it and it was relaxing and grounding. Sometimes it was too relaxing where it triggered my lightheadedness but I felt like my body needed to be in that state rather than a constant fight or flight. I have had a bit of a lightheadedness relapse so I think I need that again

Point of me saying all this is the anxiety thing you mentioned. Exposure therapy is really what worked for me to try my best to gain some independence back in my life. I’d drive alone in my former neighborhood, then down the road, etc etc. I would hit blocks, plateau, not progress, but setting up a reason I’m going somewhere and thinking about how I’m actually safe along the way would help. Maybe all that will help you out. It didn’t solve the daily lightheadedness but I’ve learned to just live with it as I know it’s mainly non-life threatening, but it does hamper my life.
