The phrase "bear up on" connotes carrying a heavy weight or responsibility, but what are its antonyms? One could argue that "let go" or "release" are opposite actions, as they suggest relinquishing control or burden. Another option could be "give in" or "surrender," indicating a defeat of sorts. Conversely, "avoid" or "escape" could be antonyms, as they suggest evading responsibility entirely. Ultimately, the antonyms for "bear up on" depend on the context of the situation at hand. Still, it's important to remember that there are times to bear a weight, and times to let go and take care of oneself.
