I feel your pain, even if you are a pain!!
I pick and bite the skin around my nails really, really badly just before my period. It's not uncommon, many of my clients do it, they don't realise until I pointed it out. Somehow the skin changes condition and becomes dry and tough, then it catches on my clothes, etc. and I start nibbling to removing the catchy bits, next thing I know I've ripped huge bits of skin off and they are bleeding. Sometimes the throbbing and pain keep me awake and night too. It's a completely subconsious habit, my Husband gets extremely upset with me as he can hear me doing it but I'm unaware until I'm soaking up the blood with tissues and complaining they hurt.
It's a hard habit to break, we're in such uncertain and scary times so it's not a surprise you are being hit hard. Use your Solar Oil and Hand cream, find a distraction if possible when you know you are picking. It's disgusting but my Husband puts his dirty socks on my hands to stop me
