Is the only way to deal with the effects of your bad karma endurance? Do you just have to endure these bad effects no matter how long they may  last? I feel like I'm dealing  with some bad karma.
Try to make good Karma - it will help you for sure. The Buddha once gave a simile.

He said that bad karma was like salt and good karma like water. If you put some salt in a glass of water it will taste bad, but if you put the same amount of salt in a river, the taste of the water will not change, so doing good karma is a very good way to handle this situation.

Of course, one can get rid of all past karma by becoming enlighten or a Buddha, ordaining would be great, but I assumed you wanted a "quick" and "wordy" answer.
