*warning for grossness*

I have a really bad habit of sticking my fingers up under my eyelids, both top and bottom, to pull little bits of mucus out. Sometimes it's not bad and i just do it randomly throughout the day. Sometimes it's pretty damn bad and I do it sitting with a mirror for 3-4 hours at a time, several days or weeks in a row, just sitting there picking at my eyes. I waste SO MUCH time doing it (prob about 18 hours this week) and I constantly have sties and infections, swollen and red eyes, and when it's really bad my eyes get really blurry. I've been doing this since I was 12 (I'm 32) and it does kind of worry me because I can stick my fingers up under my lids over and over probably upwards of 5000 times a day. This is a really stupid question, but at what point is something a "habit" and at what point is it a problem? I've been debating telling my pdoc or new psychologist but I don't know if I'm making a big deal about nothing because some weeks it's barely an issue. This week has just been really bad.
