I totally understand. As I have gotten older I realized how much of my preparation came too close to my trips. I now make lists of things to do and schedule some of the events out in advance so I don't get stressed with last minute things.
Life is supposed to bring enjoyment and doing certain things that bring enjoyment also bring stress for us as we prepare for that. I am also realizing that some things are not that important and I can postpone some things to do while camping, like cleaning it and waxing it. ;)
If you feel that getting rid of it is the answer then by all means that is what you should do but if you enjoy this lifestyle then you can rethink your priorities. Sometimes certain things become a chore, losing passion for it may indicate a change of pace.
Good luck in your health as well.
