Disabled with 3 suitcases

Hi everyone, I'm moving and am traveling with 1 large, 1 medium, and 1 small suitcase and a backpack. I've never traveled with this much stuff before and I have a disability. I'm traveling solo and am worried about having to maneuver things on my own and wait in line with a backpack after checking items. What can I do to get help getting my suitcases to the checked baggage and not have to stand for a very long time before I get to my gate?
