I go along with everything said here - and definitely no need for guilt. Absolutely none. Your contributions are helping to keep this forum ticking over nicely, and for that thank you John.
Brash has already suggested one sort of indoor closeups which can produce stunning results, and droplet photography (don't know if that's the right words for it) might be another. I don't know what your options will be out of doors as Spring turns to summer, but there are some fascinating/beautiful botanical subjects on a small scale that you might find accessible - small flowers, buds, berries, husks, fungi and lichen - either in situ or taken indoors to work with. Once you get your eye in for small stuff you tend to see much more than you ever noticed before.
Another thing I'm thinking is that scenes don't necessary pop into view just by looking around for them - I find I have to explore with the camera, trying things and seeing how they come out, because the camera doesn't "see" things the way we do, and what's more it can see things that we simply can't make out with our own eyes because they are too small, and can look from places and in directions that we can't get to.
On which score, do you have an articulated screen on your camera? This might get us into a controversial area, but FWIW I almost always use live view and all my cameras have articulated screens. This lets me get some angles that simply aren't possible using a viewfinder (not without an angle viewer at least), and many angles that would be very difficult/tiring/wet/muddy/motivation-quashing to get using a viewfinder.
This does depend though on having a camera which has a usable live view mode. (The reason I only recently got a dSLR was that the 70D was the first one that seemed, as far as I could tell from reading about it, to have a decent live view implementation.) This in turn leads me to the heretical question as to whether a dSLR is, given your mobility issues, the best tool for the job as far as closeups go. What I'm thinking is that I can capture images one-handed with my FZ200, which lets me stretch and lean into places that I couldn't get to otherwise, and while stretched out, and also one-handed, zoom to change the magnification and framing, and alter the aperture and ISO, and see the effects on the articulated LCD. Not necessarily a bridge camera of course - there are other small. light, flexible options these days. Just a thought.
