I have BPD and generalized anxiety. Since I was young (thanks to an abusive parent) I have always bit my nails. It’s become routine for me anytime I’m anxious or sometimes even bored. Half the time I don’t realize I’m doing it or feel like I can’t stop myself. I just got acrylic nails for the first time in 3 years and as pretty as they make me feel, they are SO FRUSTRATING. I’m a pc gamer and they are just making it so much more difficult. 

Can anyone tell me their tips and tricks that got them to stop? Anything other than the usual suggestions?
