How to stop bad habits?? HELP!!

Ever since I can remember, I’ve always picked at my nails & bit my lips. I have vidid memories in middle school of crying bc my fingers & lips hurt so bad. I’ve picked at my nails probably every single day for as long as I can remember. Aside from one time where I went months without messing with them & they started growing normal. My anxiety levels skyrocketed & I ruined them again.

I’ve recently noticed the need/urge to pick happens when I notice dirt or something weird under my nail or whenever I feel something rough/hard/out of place on my lips. I’m not OCD. I’m not the type of person that has to have things a certain way lifestyle wise. I have Dysthmia, generalized anxiety, PTSD, ADHD, Bipolar 2, & insomnia.

I can go a few days without messing with my lips if my anxiety levels are low. However, I can never seem to leave them alone long enough to fully heal.

I’m terrified my nails are going to just fall off bc of how much I’ve pushed them back.

These are two of my biggest insecurities. I have tried what I feel like to be everything to stop. I’ve tried nail polish, getting my nails done, lipgloss, chapstick, motion-habit redirection, consciously stopping whenever I notice, etc.

Has anybody else had these habits?! What helps you??
