As for whether or not you’re a burden, think of it this way. Humans are social creatures, which means they live in groups and support each other.

Feelings like this are what prove that we’re truly alive, as opposed to a statue that feels nothing at all. Rather, life is about coming to terms with these things and learning to keep moving anyways. After all, the only way to go is forwards
