Is anyone else here super sensitive to missing just a day or two of any of your meds? Or when taking a lower dose than normal on a particular day?

Specifically, I'm super sensitive to not taking the full 600 mg of Seroquel daily. I had a 300 mg pill last night instead of the full 600 mg, and all day I've had really bad racing thoughts. It's strange to me that just a day of not taking the full dose, I'm noticeably unstable. I've been struggling all along, but I was noticing 600 mg has made somewhat of a positive difference compared to before. Do you notice a difference when you forget or skip?
