If it's possible for you to park the boat, rent a car and drive inland
for a night or two at a motel, it may help a lot.

Also try a role play. Let's say you sell the boat. Imagine that. Then
you take a small apartment somewhere inland. OK, now imagine it's months
down the road and you've watched Judge Judy for 45 consecutive weekdays.
I suspect if you can role play this one, you'll recognize you wish to be
back aboard.

I lived aboard over 7 years. 5.5 with my now late wife and 1.5
singlehanding in a different ocean. I found I got fed up with it from
time to time but a bit of a break out of sight of any ocean made a huge
difference.

The joke is you take an oar. Put it over your shoulder and start walking
inland. As soon as someone asks what that thing is over your shoulder,
you're far enough inland. Turn around 180 degrees, return to the boat
and you'll be ready for another few months of life afloat.

Worked for first us and then me always. Consider it.
