I have started to bite the skin off my lip usually until it bleeds. Most of the time I don't even know I'm doing it. My mum has caught on to the fact I'm doing it. I think it's a resort to not biting my nails because I gave that up a while ago as I realised how horrible the habit was and since then I just started chewing my lip. I don't mean to make it bleed but I just can't stop. I have read on Google that it can be because of anxiety, I haven't been diagnosed with it but most of the time I am pretty sure I have anxiety. Should I go to the doctors about it, and how should I try and stop myself biting my lip? Is there any way to get rid of anxiety, if I have it?
