How to continue coping

Just wondering if anyone else has problems coping with who they've become?  I'm sure there  are a lot of people out there who do...but it gets so tiresome.  It le=itterally wears me out.  By the end of the day I can hardly keep my eyes open...kind of stinks, but that's how I feel.  Even before the end of the day I feel wioed out from overthinking everyting.  So here's hoping that changes after my next med evaluation.
