Better or happier

I was thinking out loud again, the advantages of living alone. Like someone is going to hear me let alone answer. And the old saying, if either happens, you're in trouble. Anyway, I was wonder if it's better to be or feel better or happier. Feeling better is relative to where we are mentally and how we think. Feeling happier is the state of the feeling, relative to where we are emotionally and how we feel.
