For me this is really true. I'm more of an introvert, and I don't usually reach out to others very often. It can be in the form of talk therapy in a formal setting with an actual psychologist. It can also just be catching up with a friend, or chatting with a neighbor about something totally unrelated. Anything that can get me outside of my own mind helps. Looking for opportunities to help or become involved in someone else's life is really helpful.
