Not only you. Best thing to do is to occupy yourself with something to do. Prepare plans for a day if that's necessary, this will help a little bit - people generally function better when they know what to do and when. It can be something simple like:
6.30 - get up
6.45 - excercise
7.15 - breakfast with family
8.30 - check email
9.00 - work/learn
16.00 - free time
17.00 - call Mom & Dad
Etc.
That's something that I'm normally doing with my little son, he have some problems with concentration etc. and daily plans help him a lot with emotions, he feels safer when he knows what will happen every day.
Other than that - make a list of things that you're afraid of right now with the steps that can make that better and are actionable. Then do it.
