The antonyms for the phrase "hanged up" would be "resolved" or "unburdened." When we are "hanged up" on something, we are fixated on a problem or issue that we cannot seem to shake. We feel overwhelmed, stressed, and unable to move forward. On the other hand, when we are "resolved," we are able to make a decision and move on confidently. We have found a solution or come to terms with a situation. Similarly, to be "unburdened" is to be free from the weight of stress and worry. We have let go of our troubles and can move forward with peace of mind.
