Loneliness are of 2 types: either you feel lonely because you're alone or feel lonely even in presence of friends. Identify which situation you are in. The first can be solved quite easily, such as: 1) read a motivational book 2) listen to some up-tempo song 3) play with your pet 4) participate in a social gathering 5) write a letter to a friend 6) cook a nice dish 7) comment on a blog If one feel lonely even in the company of others, you need to find new friends or try to reconnect with your friends. Cheers!
