Hello. For the past month or five weeks, I ve been experiencing severe depression and insomnia. In the past four weeks, I have had four nights when I did not fall asleep at all. I think I m showing signs of bipolar disorder. My depression comes and goes in waves. It seems like every three or four months I get hit with a debilitating case of depression and I can t work or even get out of bed some days. I have also been experiencing some issues with sudden muscle twitches and even feel like my brain gets shocked when I try to go to sleep. It is not painful but I m worried.
