Pfrog, you're really on to something there, I think. Selfcompassion is a very important part of life! However, I still find it hard when you're desperately trying to quit a habit and not really getting anywhere... (especially when combined with a perfectionist nature).

A friend of mine recently gave me some very good advice. She told me to stop taking non-picking as the "normal" way of life (since, clearly, that only makes me beat up myself and get miserable) and start seeing my picking as the normal way - or at least, the dominating way in my life right now. In thinking like that, any day in which I don't pick will be a huge success and a deviation from the rule!
That's actually a way of being gentle and kind, I think.

Also - I came up with a new trick together with my mum: I get to pick one spot every day, but only one! So I need to make a tough decision of which spot drives me crazy the most and where I will pick, and then I can act on the urge - but only in this one tiny place. I thought it wouldn't work, but as of today I've been doing it for 4 days and it's going really well!
It gives me the freedom to not have to stop completely straight away (and the mental idea that "I'm still allowed to pick") whereas the negative consequences are severely minimized and my skin looks a lot better already.
Fingers crossed to see if this will keep working
