I am a people person but that doesn't mean I dislike being alone at times. We should all learn to handle being by ourselves and we will then be even better when around others. I can feel more alone in a crowded room than an empty house.
A lot of people feel the need to have some sort of distraction present to fill the silence of a room, like constant tv or music. I think that can be a negative thing. Are you ever alone with your thoughts? Can you hear God's whispers above the noise? Some people sleep with earplugs to get a good night's rest but sometimes we should try a daytime pair to block out the world.
Only when we are happy with ourselves can we make others happy. I encourage you to 'be still' and get to know yourself and your thoughts in some quiet time. God is with us, so we're never really alone.
