The Gospel Coalition have just published an article of mine: How to care for friends with anxiety and depression. See the whole article here.
For the practical section, these are my headings…
Get them talking (Prov. 20:5).
Check on their self-care (1 Tim. 6:8).
Break down their worries (Luke 12:32).
Break down their tasks (Matt. 6:34).
Help them build new routines (Prov. 15:22).
Make a “coping bank” with them (Rev. 2:4–5).
Don’t offer false reassurance (Jer. 6:14).
Ask about their mental diet as well as their physical needs (Phil. 4:8).
Challenge false guilt (1 Pet. 3:6).
Make the spiritual simple (Matt. 6:7).
Communicate hope (John 16:33).
