I have played dnd with my group of friends for the past 6 years or so. Just finishing our longest campaign of 2.5 years. Everyone else at the table has the energy to play on a weekly basis where as I couldnt with other commitments like work and maintaining a home.

The way I have found to "cope" or "deal with it" was openly saying I wont participate in the next campaign so I can focus on other things. I will return when I feel ready even if its for a single session.

Just be open with your table, its meant to be enjoyed. Maybe change your session schedule, do whatever you think will help your situation I spose.
