I do a lot of weird things and when I read online they all say that they are anxiety caused or whatever. Some things I do are bite my nails, bite my cuticles, I have to have gum all the time, I sort of pull my hair out, I pull on my eyebrows and eylashes. I feel like I have anxiety attacks. I have a lot of stress in my life, but what teenager doesn't? Is doing all this stuff bad or is it just normal for a teenager to do?
