Is one of your friends, or your boyfriend or girlfriend, not doing well?
Ideally you would like for them to get help, because you can’t solve all their problems. An expert can offer such help, for instance by listening closely and finding solutions together. Talk about it with your friend. They may not have considered the option of getting help yet. Motivate them not to go through all of it alone. Sometimes an initial conversation can have an effect, and you can make a big difference by nudging them in the right direction.
