I have been feeling the exact same way, lately. I used to feel I was constantly failing at work no matter how hard I tried because there was always something to improve on, always someone who I didn't get on with. Only now have a I started to realise how co dependant I was being by beating myself up when I couldn't please someone or wasn't the best. I would accept unacceptable bullying behaviour.
Now, I have stopped valuing myself by what others seem to think of me. Surprise surprise, I am doing much better at work and am actually enjoying my job again. I have even asked for a pay rise for the first time in my life. I got overlooked last year when I allowed myself to be bullied by a previous boss. SR has shown me that I don't have to accept bad situations as somehow deserved. I have the right to stand up and be respected for the wonderful things I can offer.
Just wanted to share that you're not alone in finding other aspects of your life are getting better. SR is a place of much wisdom!
