When I started to feel very unwell, I went to my general doctor. That ultimately led to a refer all to my psychiatrist. A lot of your symptoms resonate with me and your are in my thoughts.
Under the circumstances, seeking medical attention is likely the best thing you can do. This is only my opinion, but I highly recommend seeing a psychiatrist if you are not seeing one already. Therapy can augment this, as well, and be part of your treatment team.
Regular insomnia and erratic food intake wreaks havoc on me. I'm no stranger to attempts and I have bipolar disorder. I'd get to a psychiatrist ASAP. You are in my thoughts, Hadley.
