Brightstar, what a great move going out with your cousin and laughing so hard, your heart must have chosen her on purpose knowing you needed that!
I'm 2 1/2 weeks into no contact (although I did *clarify* a week or so in), and my whole body ached a LOt of the time the first week but a lot less now.
I think doing things like you're doing, putting good things in your day that are part of the life you want to have, help a lot. Not as a distraction -- because as people here said you do have to feel all that and it's healthy to feel it so you can work through it -- but for balance. To have something good and positive and aiming toward you in your day, every day.
Big hugs to you. Do something kind to yourself and self-loving tonight.
