I've been on vacation for a week. Spending time with my sisters.the three sisters got together to celebrate the 50th birthday of the middle sister.it's been fun But very stressful.their successes just magnify how much I've lost in the last 3 years. I know they try to understand I've just feels like I'm the biggest loser in The family. I am trying to keep them from seeing my pain. What else can I do ?
