I've learned a few techniques on how to cope with pressing thoughts. I've had to use them because I've been so worried about the sudden switch to going completely online. 

1. Make a list of future events that you're worried about. Write what you think will happen/why you're worried and then write what actually ended up happening. (This one has especially helped me)

2. Mentally take a step back from yourself and think about the big picture and if all this worrying will change anything in the long run.

3. Go outside and enjoy the weather. Whether it's taking a walk, going for a bike ride, or whatever, go outside. It's amazing how much your atitude can change in just a half hour of good weather.
