Being aware of your body language helps you convey what you are trying to say more accurately through non-verbal movements. It helps give authenticity in what you are trying to say.
Hope this helps!
Always ask how they are feeling?
How are they coping?
Do they feel sad/depressed?
If depressed, maybe ask if they've been given medications?
Ask if there emotions prevent them from completing tasks, or if life in general has become more difficult due to them coping?
