When I was little (without knowing I had BPD) I use to say I wanted to get an operation on my vocal cords, so I could eliminate my voice and not talk. 

Now I know that I did that because I overshare/overexplain. Sometimes I still wish I could somehow eliminate my voice as to not talk and not overshare anymore.

Does anybody experience something similar? Any idea on why BPD patients do this? How do you reduce oversharing or overexplaining?

Thanks in advance!
