The first thing is to know the signs of mental health problems and be able to identify when someone needs your help
Once you have identified the problem, you can offer your support in various ways. For example, if they are feeling low, you can send them a friendly message or a call to check up on them and make sure they are doing well
The other way is to introduce them to different methods of coping with stress or anxiety — show empathy by listening and validating their feelings without judgment
Lastly, if they are struggling with suicidal thoughts or tendencies, it’s important that they seek professional help immediately through a therapist or psychiatrist.
