(((Squiggle))) I still battle with this same issue of having unrealistic expectations of myself and discussed it with my T (She was the one that really noticed it).
She said a few pertinent things to me:
No-one is perfect - that's what makes us human and gives us character.
Can you take the things that you see as negative in yourself and find anything positive in them? You usually can - it's all about making your 'weaknesses' into strengths. It's merely a mindset change.
