A lot of people who are feeling lonely can alleviate their symptoms by joining a club or a group of some sort, whether it is online or a face to face situation. There are lots of workshops and courses happening, online and offline, that are open for anyone to join. It does not matter what the activity might be; perhaps you have a hobby like literature, music, or cooking, or any kind of sports-related activity, such as dance or yoga, for example. Simply mixing with others on a regular basis will lower the sense of loneliness anyone might feel. The feeling of belonging to a group is not to be underestimated as it can truly have a positive impact on someone's mental well-being. Pets and even robots that interact with you can help to deal with this emotional state, too.
