Here is what he could do to his depressed friend:
Let your friend know you’re there for them. You can start the conversation by sharing your concerns and asking a specific question. For example, you might say, “It seems like you’ve been having a hard time lately. What’s on your mind?”
Keep in mind that your friend may want to talk about what they feel, but they might not want advice.
Engage with your friend by using active listening techniques:
Ask questions to get more information instead of assuming you understand what they mean.
Validate their feelings. You might say, “That sounds really difficult. I’m sorry to hear that.”
Show empathy and interest with your body language.
Your friend may not feel like talking the first time you ask, so it can help to continue telling them you care.
Keep asking open questions (without being pushy) and expressing your concern. Try to have conversations in person whenever possible. If you live in different areas, try video chatting.
Your friend may not be aware they’re dealing with depression, or they may be unsure how to reach out for support.
Even if they know therapy could help, it can be daunting to search for a therapist and make an appointment.
If your friend seems interested in counseling, offer to help them review potential therapists. You can help your friend list things to ask potential therapists and things they want to mention in their first session.
Encouraging them and supporting them to make that first appointment can be so helpful if they’re struggling.
