If you feel yourself getting upset or tense, use some calming techniques before talking to your friend. Taking slow, deep breaths is a well-known way to reach a calm place. You can also try counting backwards or actively counting your breaths. This will distract you from a stressful situation and help you center yourself. [2] X Research source

Make sure your tone says you are asking because you care. You can try stating what you see, then asking if everything is alright — “You don’t seem to be yourself today. Is everything OK?” or “Your reaction seemed a little over-the-top. You OK?” Your friend might not be able to articulate what is causing them to feel sad one minute and happy the next. But just trying to put it into words will often take the emotion out of the situation and help your friend get back on an even keel.

If your friend asks you to leave, be sure to check on them later. You don’t want them to feel abandoned.

Some moody people use their moods to control their friends and gain attention. If you feel you are always tip toeing around a friend, and always the one who is making compromises to avoid a scene, your friend might be manipulating you. Be kind, but don’t feel you always need to do things their way just to make them happy or avoid drama.

Some signs that your friend needs more help than you can give include uncontrollable sadness, anger and crying. Uncontrollable laughter and manic highs are also signs that your friend’s mood swings are more serious than normal.
