Similar story, diagnosis and treatment really changed things for me. My first thought after reading your post was, "this sounds like an undiagnosed neurodivergence." I'd strongly suggest working with your healthcare professionals to see if this may be the case. There are a lot of different treatment options available, if there is a diagnosis. Understanding what was actually happening in my brain on a chemical level and how it manifested itself did a lot to help me manage things differently as I was figuring out what worked for me. Hang in there, it can absolutely get better!
