Well it’s great that you want to make that effort to stop! The best thing to do is to figure out what your triggers seem to be, and where you tend to pick the most. Do you find that you pick at certain times of the day more than others, or maybe pick more when you feel a certain way? Whenever you catch yourself wanting to pick, write it down, write the time down and write what you were thinking/feeling (and perhaps what you had been doing prior to that moment). And then try and see if there’s a connection between stuff in your life and the picking. If that doesn’t help, the best thing would be to avoid the mirrors in the places where you pick the most, and only look in the mirror from an arm’s length away or further. Wearing gloves also helped me when I just felt like I couldn’t stop feeling my face for breakouts, as I’d then not be able to actually touch my breakouts or pick at them. And doing other activities helps to take the mind off of it. After a while of just forcing yourself to not do it, it gets a lot easier.
