When it comes to the idea of losing control, there are plenty of synonyms to choose from that can help to describe the feeling. For one, "unravel" is a great synonym to use, as it suggests that things are falling apart and getting out of hand. "Spiral" is another good choice, as it implies a sense of things getting worse and worse over time. Other synonyms might include "slip," "descend," "collapse," or "breakdown." Ultimately, the words you choose will depend on the specific situation at hand, but any of these synonyms can help to paint a picture of losing control in a powerful way.
