Stay with the person and let them know you’re there for them and supporting them. You need not talk much, just your presence is enough, especially if the person feels there is no one for them.
If they seem uncomfortable, ask, “Would you like to go somewhere more private?” You can take them to a bathroom stall, car, private room, anywhere, but not in a place where there will be dozens of other people. If you’re still young (school or college), don’t take the person to a place where you’re not supposed to go like a classroom where no one is having lessons. Also make sure you can find your way out. Don’t want to get in trouble!
You can say, “Would you like me to get you a tissue?” Sometimes, giving a tissue is a sign that you want them to stop crying immediately. Be careful how your actions may be perceived, especially when the person is very upset or dealing with death or a breakup.
You might feel awkward or uncomfortable around someone who’s crying. Remember that your role is to offer support in a way that’s helpful to them, and the focus is ultimately not on you.
Ask, “What can I do to help?” or “How can I support you?” If they ask that you leave, leave. Refrain from saying things like “But you need me to help you!”, rather just say “Okay, fine but if you need something, call or text me. " People need space sometimes.
Don’t stop for a few moments then get on with your day. Stay with them and let them know you will stay if they need you. Even if you have work to do, giving a few mins extra won’t hurt.
Ask, “Mind if I hug you”? Your friends or family may want physical touch more than strangers, so make sure you don’t make the person more uncomfortable.
You might comfort someone who never tells you what’s upsetting them. That’s okay. You could just say, “Talking about a problem would make you feel better. If you wanna talk, I’m here with you. " Don’t be or act judgmental.
Improve your listening by making eye contact and responding nonjudgmentally.
You might really want to relate to them or talk about something in your life, but resist the urge to do so unless they ask. Your role is to help and comfort them.
Their crying is not a way to solve their problem, it’s a way to express their emotions. Let them do so without interfering. This might be hard if you generally try to avoid crying yourself. Remember, crying is not a sign of weakness.
For example, try saying, “It sounds like what you’re going through is really difficult. Have you thought about talking to a therapist?”
