Everyone is afraid to take some vacation who have a startup. I think that this situation makes things even worst and then you think that you had enough but in the opposite site you afraid to leave for some vacation and put yourself in an endless loop. Depression is coming...

Take some days off. Soon you will understand that everyone respects your vacation. Don't afraid to pick up the phone and give solutions where it's needed while you are in the middle of your holidays. Picking up the phone will make you feel comfortable.

And always remember: Everyone respects your vaction. Don't afraid to leave for some days and relax.
