Nature lover.. even if you lost a foot that does not mean you have to give up travel. Threre are hand control kits if you cant use your feet. There are prostetics too. People in wheelchairs go solo camping in cars and minivans as well as RVs. You would of course need some temprary extra medical care and some physical therapy but it absolutely does not have to mean moving into a nursing home. You are scared and you have a tendency to feel like the worst outcome is going to be your fate. That is a combination of factors that can lead straight into depression, which you can't afford to be doing if you want to live an independent and peaceful life. The one thing you can do about it is force yourself to quit the doomsday thinking cycle. That is within your control to do, when you start down into that cycle mentally tell yourself the wded, enogh., sto, shutup or whatever word makes you quit. It takes pracrtice and at first y ou might have to do it nearly every hour or so but in a few weeks you will get better control and break the doomsday thinking habit. It is a very non productive bad habit but that is exactly what it is, a habit and it can be changed.
