Two thoughts.

Watch out for martyrhood. Indulging in it can definitely produce the kind of experience you describe.

But if you're sure that's not the problem, I'd suggest simply not associating with anyone who takes advantage of you. In a business context, this can mean "firing your customers", as someone once put it.

I am sure I am not personally inclined to martyr myself. I am equally sure that does not prevent other people from trying to cast me in the role.

I have had a long day. Minor emergency came up. Catch you later.
