With me (and I think a lot of people) it sort of feels like very happy, thrilling, queasy butterflies in the tummy. :) It's an actual physical sensation which is at least reminiscent of feeling a bit sick, but in a good way. It sounds odd but I've heard many people say similar things.
It makes life worth living, I know that much.

Love is not all about happiness and lovely moments, it about still loving someone, valuing who they are, and caring about them more than yourself, even if they don't reciprocate those feelings, and even if they let you down.1
