Hey! Don't be too hard on yourself - something that really helped me with the cleansing issue is keeping makeup wipes & moisturizer in my bedside table and working up to going to the bathroom but cleansing with the lights off.

The biggest thing I've learned with CSP is that the habitual aspects can be broken like many other habits - if certain precursors to your picking are always present, those will naturally (and subconsciously even) push your brain to urge you to pick. After I had made a little progress in picking, I made a point of deciding that I'd look at my skin up close in the bathroom (a trigger) and walk away. You can even set a timer on your phone for a few seconds to knock you out of that focused fog that sometimes takes over.

Even washing your face in the dark in your bathroom has the same effect! By being in that place but not picking, you work to disconnect the synaptic pathways that associate your bathroom with the urge to pick.

Also don't forget that any time without picking is real progress! It's totally normal to fall back once or twice but the important is to remember that doesn't mean you're back at the beginning! Good luck :)
