Can’t even coach myself

It seems like the more I get coaching and coach myself on certain topics like my relationship, the worse I do (as far as actions towards my partner and my mental state) and the unhappier I get.  I’m having thoughts come up constantly about how I can possibly help anyone else when I can’t even help myself. I know this is not the mindset that will help me be the coach I want to be but I haven’t been able to get out of this spiral yet. Help!
