Maybe making a plan for some "me" time when you get home will help. A day at a spa or joining an interest group or finding a new hobby...something that will be all about you and take you and your mind away from your troubles.
Just as our minds clear when we go away and relax and find peace, they can remain clear at home if we take very good care to relax and find peace there too.
However this unfolds, LMN, we're walking with you. I hope you have happier days ahead.
Hugs
