It seems like you bite your nails, maybe b/c of anxiety, but instead of asking for help, you want to know if you should feel anxious about the repercussions for it!
Try to find some time to relax, either deep breathing, exercise, or a hobby. Definitely take a walk on shabbos, where you can relax your mind and stay off your nail biting.
I hope that it’s therapeutic for you to air your question in the cr; I also hope that you are not constantly concerned with the hot place. While it’s important to know, learn and remember schar veonesh, it’s unhealthy to live a life of anxiety based on it. Instead focus on ahavas Hashem, how you are trying to break a bad habit because you love Hashem and are trying to please Him.
