My loneliness is my companion

This feeling of loneliness that is manifesting itself withing me is what reassures me that I am still alive and that although I feel dead I am merely on auto pilot. It’s a painful feeling that feels as though my heart has imploded and I walk around with this accepting it as a part of me, like an extra body part or some weird thing like that.
But I don’t want loneliness to spread and grow inside the people around me, so I’ve taken it upon myself to put a smile on the faces of people who look upset or just any random person in general. Just because I am denied happiness doesn’t mean anyone else should be denied that right too. Maybe I’m stupid and naive but seeing someone smile because I made them smile makes me feel human and whole for a few seconds and hopefully they feel the same way too.
