I need advice on dealing with someone's moods?

You're a good friend: Dealing with someone who has changeable moods can be very challenging; you are very kind to want to know how best to help. You need to walk the fine line of being supportive without enabling: avoid confrontation, offer to do something you know the person likes, offer to talk, be caring. Don't dig into the cause and question the person.But you need to walk away, without guilt, when it gets too much

Help them get help: Keep the communication channels open and suggest taking the moody person to a counselor, social worker, therapist, psychologist, or Doctor for help. Make sure the moods are not secondary to a medical condition like Hypothyroidism for example. If the moods are secondary to Bipolar disorder there are treatment options. Help the moody become stable and happy.
