A troubled person or situation has problems or difficulties that make them feel upset or worried. They might be struggling with their emotions or facing challenges in their life.
When we say someone's mind is troubled, it usually means they're thinking about something bothering them a lot - maybe a bad event, a tough decision, or just feelings of anxiety. It's like when you can't shake off the worry that's stuck in your head and keeps coming back to haunt you. A person might also be described as troubled if they have personal issues, like addiction or mental health problems.
To disturb, stir up, agitate (a medium, especially water).
Anxious, worried, careworn.
