A lonely person needs strong, optimistic friends. Negativity, sadness, and loneliness can easily spread—think of them almost like social diseases. Make sure that you’re a positive influence. This can be a lot of work, especially if you’re not naturally cheerful, but it can make a world of difference.
Likewise, happiness and energy can be infectious, as well. Inspire them! Talk about things that excite you, and things that you know excite them. If the conversation begins to turn negative, turn it around.
For example, if your lonely loved one went through a recent breakup, you can remind them that they’re still a valuable, whole person, even by themselves. Don’t let your friend descend into spirals of negativity. When that negativity comes up, do your best to naturally replace negative thoughts with happier ones, or at least affirming ones.
Sometimes, people just need to be reminded that it’s okay to be happy.
