Ill be blunt.. I understand how you feel I do , been therre before , but your keeping yourself unwell with this constant looping and ruminating.
Get
outta your own head, Stop thinking and being worried about YOU , Just STOP. Worry about your wife , your kids, your pets, your plants.
Seriously just get out of your own head. It will do you a world of good.
If you wake up and your brain starts down that road " do I have bipolar? Just Stop... turn around , Think about your favorite movie, or food or desert .
Just stop.. You can and will feel better, But you have to step out of the dark dreary corner you spend so much time in.
