Getting out from under a task or a problem can be quite challenging. However, there are also instances when you don't want to get out from under certain situations or people. In such cases, antonyms for "getting out from under" would be to "embrace," "accept," or "welcome" the problem or person. By doing so, you can learn to coexist harmoniously with whatever it is that is causing you stress, rather than trying to escape from it. Sometimes, it's best to face your fears and challenges head-on, rather than running away from them. In those situations, the opposite of "getting out from under" would be to "confront" or "tackle" the issue or person in question.
