The best way to support someone with a mental health condition is to be understanding, patient and supportive. Here are some tips: 

1. Listen without judgement: let them know you’re there for them and listen without concerns or judgement. 
2. Offer practical help: offer to help with errands or tasks that may be overwhelming 
3. Encourage professional help: if you think they would benefit from professional help, encourage them to seek it
4. Connect them to resources: share information about mental health resources that could be helpful.
