i am biting inside my mouth. how can i stop that?

June 7

I have this weird habit for 10 years. I do not have any serious mental problem. I am biting the inside mouth surface till i make it bleed. Sometimes I tear off very small pieces from the inner surface of the mouth. If i bite it for days, my mouth hurts for about a week. I really want to stop biting my inside mouth but i can't. I bite the inside of my mouth completely consciosly. Sometimes I can't talk or eat or drink water because of the pain. I need your advices. This habit is ruining my life. Have a nice day!

Thank you bro. This is my first biting-free day. I will try to find the inner reasons. And i realised that my mouth is always dry. I am going to remake my water drinking habit.

UPDATE AFTER 6 MONTHS:
I hadn't done it for a long time and it started again. But now I haven't been able to stop myself for a week and I continue to bite. I'm trying not to bite while writing this, but a very strange feeling is pushing me to bite the inside of my mouth. Damn, my 6-month streak is broken. It really sucks. I need to stop biting now but it's so hard. Damn. I've been so stressed out for the last 2-3 weeks and I can't control myself.
