Roller Coaster

Ok so first, I failed at disconnecting / unplugging from everything.  I made it 10 minutes.  For the past few months I've been on this roller coaster ride of emotions.  I am really starting to question whether I should seek professional help.  One second I'm happy and cheerful, the next I'm all in my head over analyzing and twisting events causing me to be depressed.  WTF.  Can't I just be happy??  Can I please get off this roller coaster??  Why do I over think??  I really wish I could just turn off my brain sometimes.  I want to enjoy life instead of stress over it.  Ugh.
