Overestimated breasts

Ok so I scratch and pick when I am nervous kind of like as a stress reliever. I used to pick my scalp until it bled but now I scratch my boobs and like I have pimples on them and I literally cannot control myself once I see it its gone. Anyway I noticed that lately that after my breasts have like a yellow liquid substance coming out of them?? Is this breast milk? If so how do I make it stop!

Plz be nice I have severe depression and anxiety disorders and this is an unfortunate side effect I do not do this on purpose I often don't realize until there is blood what I did. I think its called picking disorder (related to OCD) or something idk??

Any suggestions would be great ❤
