Changing bulb on hanging fixutre?
I doubt that you damaged the fixture. You probably loosened it from the electrical box it's attached to. Usually the bulbs can be changed without removing the fixture from the wall. Turn the light off (because it gets very hot) and try to push up the fixture and rotate it in the opposite direction to correct what you did before. Get a ladder, not a chair, and get up there close so you can see what's going on up there and where the bulbs are.
