Stress can sometimes lead to bed wetting in both Children and Adults so it's possible that if you're suddenly wetting the bed and you've been stressed out that the stress could be a cause of your sudden bed wetting as an adult.
Although I would get checked out by a doctor to be sure the bed wetting isn't caused by an infection or other bladder problem.
As an adult having sudden bed wetting isn't normal so I would recommend seeing a doctor to rule out anything serious.
Your doctor can also prescribe you medications to help stop the bed wetting.
