Vitamin concern

37WM 6ft. PMH of sleep apnea, ADHD, anxiety, depression, hypogonadism (untreated), low vitamin D (untreated). No surgical history.

I don’t really consider myself anorexic. I had an emotional breakdown a few months ago and was unable to eat for a while (2-3 weeks of mostly yogurt). I was crying a lot and it was hard to swallow and I just didn’t have an appetite. when I started back to eating it was like the habit was sort of messed up. I didn’t have as much of an appetite for a couple more months. I was still a basket case and that probably contributed. My appetite finally returned in August. But some part of me liked the weight loss and I needed help to press on, so I got a glp-1 RA off the internet. It was maybe more effective than the emotional nonsense. So all and all I went from 255 to 208lbs since May. In the past week I have noticed that my heart is doing strange things when I stand, I get seriously lightheaded. this morning I was sort of shaky like Parkinson’s person. I feel like there has to be a vitamin deficiency or something. I just went to the grocery and I was just so foggy. I couldn’t concentrate. When I got to the self-checkout I couldn’t remember what I had in my buggy and really why I went to the grocery store in the first place. Does this sound familiar to anyone?
