anewbiewannabe, my heart goes out to you because I too have multiple chronic health issues, but I also have a loving spouse, thank God, and with his help we're still able to travel and work and contribute where it's needed.
While reading the responses on this thread (I love this forum; there are so many good-heated members here), one persistent thought kept looping in my mind. Have you ever thought of sharing your adventures with a friend?
There does seem to be rather a large number of members even here on this one forum who have health issues too, and the kind of health issues that are preventing them from taking to the open road. If I didn't have Brian (my husband), I'd at least try that tactic, even though I'm probably a definitive hermit/loner (and no, living my life center-stage doesn't make that untrue). If I wanted to travel badly enough, I'd find a friend to share the journey. Vehicle expenses would be halved, for a start, and having someone with you who understands physical challenges would be comforting and safer - for both parties.
Just thought it was worth a mention. If you don't like it after a year, you can always change your MO.
There has to be someone 'out there' who would jump at the chance to travel with you, someone with whom you are compatible in terms of needs and personal preferences (wants, likes, dislikes, abilities, etc.).
I'll keep you in my prayers.
Shalom,
Jesse.
