I really understand how you feel. That is exactly how I have felt many, many times. Have you had any treatment yet?
The last time I felt like that, a couple months ago, I finally went for treatment. At first I went to a Psychologist (T) and then was referred to a Psychiatrist (Pdoc). Just talking to the T was refreshing because I was finally seeing that maybe I could get some help. And the Pdoc has helped because the meds are getting me some much needed sleep and I'm less chaotic in my moods.
There is hope that you can feel better
