21 year old female with tricto/trico :(

After having finally remembered to do a little research on my obsessive habit of plucking my eyebrows, I quickly joined this website to find out other people's ways on overcoming the embarrassment and getting help. I never really thought this was all much of a problem, other than having virtually no eyebrows which I and most people who know me have come to accept and view as "normal", for me, at least. Until, that is, I discovered trichophagia. I have NEVER spoken to anyone about this, but ever since about grade five, I found myself biting the hair off my arms. The hair that is reachable has become stunted and the tops of my arms look hairless, although the hair is just very small and for the most part very blonde. I will seek out the dark hairs, no matter how short and attempt to rip them out with my teeth. Seeing photos of trichobezoars have made me very nervous of this habit now, however small the hairs on my arms may be. I do pull some pubic hairs as well, especially after suffering from a case of folliculitis from a brazillian gone horribly wrong. I never eat the hairs I pull, and I don't consciously WANT to eat the hairs I bite off my arms, but because theyre so small and I've become so used to it, it doesn't really bother/occur to me. First, finding someone who has maybe similar habits would be comforting, and then to find out how I can go about stopping this before its all gone too far.
