ive been having these weird twiches for about acouple of years now. and i worry so much about thethe one i cant get rid of is i usually biting the inside of my lips, it gets pretty bad and i do it until it bleeds sometimes. im usually pulling out eylashes and eyebrows. my binging and purging has stayed the same i usually do it about 3 to 4 times a day. can these two issue be related? input is appreciated
