What gives your life meaning?

This is the question that my therapist wants me to work on right now and I'm having trouble with it. I thought that it should be this other person who I might not ever get to be with, even if I don't get to be with her. But my therapist said, basically, that it's a waste of a life. She thinks it would be good for me to find meaning in something else while I'm waiting for her, and in case we never get to be together.

Everything that normal people find meaning in, kids, work, partner, family, etc. don't give me anything. I've got hobbies but I can't say that they give my life meaning.

Honestly, I think I'm okay with a meaningless, "wasted" life spent waiting, but I do need to give this an honest effort
