I (22F) have been dealing with persistent state of dizziness/brain fog/lightheaded/depersonalization for the past going on four months. I have had barely any appetite, I have lost weight, I am starting to have very frequent and severe panic attacks, and I have just recently started having migraines every day. I am undergoing tests, I have gotten all of my my vitamin levels tested (all within perfect range except high in folic acid), I have gotten my WBC and RBC levels tested (all good) as well as other blood tests. I have basically gone through so many tests and so far, everything seems fine. I am going to be getting an MRI and echocardiogram soon but that's not for another month or so.

The dizziness/lightheadedness that I feel is best described as an unbalanced feeling, like walking on a boat. My head feels a heavy pressure, and sometimes I get a weird "dip" feeling in my head that literally knocks my breath away. It feels like I'm going down on an elevator, when my body is perfectly still. 

Anyways, the point of all of this is, that I am absolutely petrified of passing out, and this feeling constantly makes me feel like I'm going to just lose consciousness. I don't know what it is that makes me so afraid of passing out, I think that I'm worried I'm going to hit my head on something on the way down, but sometimes I feel this dizziness while laying down in bed and I still panic. I went to the ER for a horrible panic a few weeks ago and while I was laying in bed, I was screaming and crying that I was going to pass out like it was the worst thing ever. The nurse was so confused. She was like, "you're laying in bed right now, and you're at a hospital. This is the best situation to pass out in. So just pass out" like it was no big deal. I see people on Tiktok who pass out all the time due to POTS or other illnesses and they are very casual about it. I'm terrified to drive because I'm afraid I'm going to pass out, every time I'm in a public setting I worry about passing out, even when I'm alone in the comfort of my own bed, I worry about it. 

Knock on wood, but I have never passed out before, and I really hope that I never do. But still, I would like for people who have passed out before to share their experiences. I know it's not an amazing feeling but I treat it like it's the worst thing that could happen. It significantly worsens my anxiety which then worsens my symptoms and it just makes me absolutely miserable. Does anyone have any tips to help, any knowledge, or experiences to share?
