We call this a CIV 'Critical Inner Voice'. Its alright to have one. We (mostly) all do. Its what keeps us in check and allows to live amongst other humans. Unfortunately for many of us, this voice takes precedence over our self-soothing, self care voice. (Again most of us have this). Now what we know about the human brain is it responds positively by making positive statements (even if you don't believe it). So what we might try to saying 3 self soothing comments to ourselves in a mirror. So do this, 'I am doing the best I can', 'I am the best version of me I can be' 'I am alright'. Try it. The CIV will try and jump in...thats alright, it just wants attention. Just try the positive self soothing statements once a day.
