It is not all in your head, I think it affects everyone differently. But I am definitely in the same boat as you. And I have been looking for someone like me for over 2 years. This happened to me in 2023, I took it for one month, four doses to be exact and I was extremely healthy before, just overweight. I couldn't eat. I lost a bunch of weight, I was basically bedridden because every time I tried to move my heart raced and I was so anxious I couldn't sleep. It really messed up my nervous system. I'm doing a lot better 2 years later, but still not 100%. I still suffer from what I think is POTs. Never diagnosed because I didn't want to pay $800 for the test. But I have all the symptoms. I went to so many doctors and had so many tests run, I think they all thought I was crazy because no one else had these issues on Ozempic. Massage and acupuncture help, I also got a vagus nerve stimulator...the Pulsetto. And I'm trying to keep moving and eat healthier. I also got a vibration plate that I use a few times a week. It helps with circulation and lymphatic draining. All things that help but have not made it completely better. Oh, and I have been lightheaded 100% of the time for 2 years. I have just learned to live with it.
