Resting should be easy. But it isn’t. You have acclimated to the strain and load of exercising several times a week.
With your competition coming up, the load is decreased and you may even have days off.
A lack of confidence can mean a return to the gym and overdoing it and blowing your peak. Trust in yourself and your programming and know the work you have done will pay off.
The other problem will be the ache of the taper. You have become accustomed to being tired and sore. Now you are sore in a different way. You are not pushing and pumping blood through tissues so your body is sending you new messages your body might interpret as soreness and ache.
Relax. Eat. Sleep. Taper. Recover.
Warm up on competition day and enjoy how sharp, strong, and explosive you are. You earned it.
