Denise,

I enjoy your photos, and hope you will find a way to continue.

I own the SL2 to use at times when the full-frame gear is too heavy. It weighs 16 ounces. This is 3-4 ounces more than the small Canon mirrorless cameras, but still very light. It has a good crop sensor, equal to ( I think identical to) the well-respected 80D. It is thicker front-to-back, but if you need a lens adapter for the mirrorless, the sizes become very similar.

It is compatible with any Canon EF or EF-S lens without need for any adapter. When I want the lightest rig, I attach the Canon 24mm f/2.8 STM. Sometimes I also carry the 50 mm 1.8 STM when I think there will be portrait shots of family members.

I found it easier to grip than the mirrorless cameras. The Vari-angle screen helps to avoid the need to make awkward bends with your back or neck.

The center focus point performs well; the others may struggle. Obviously there are many specific features that are better in the heavier, more expensive cameras, but most of those become important only for fast action.

Best of luck to you, whatever you decide.
