Welcome to Cancer Chat. I'm sorry to hear you are going through this. It is perfectly natural to worry - uncertainty can be really tough. Are you expecting to get the results soon?
It's best to try to do something to take your mind off the worry - something you enjoy or that distracts you. You may even find that working is a good distraction for you.
I hope you find peace of mind soon. And hopefully some others will be along here soon who have gone through similar experiences.
