Without having seen your wheel:
1. Can you loosen all of the spokes and bend the rim back straight - maybe in a doorway? If so, get it as straight as you can, tension and true the spokes.
2. (My bet) If the above doesn't work, cut your losses and buy a new wheel. If it's a front wheel you might have luck finding a used one. Trying to use the spokes to pull a bent rim back straight isn't likely to be a lasting repair.
