Why grrrrr at you for having feelings? Being sensitive to rejection is painful. Your sensitivity also makes you a wonderful friend. There are drawbacks and payoffs. Maybe you could work on your interpretation of those rejections and find a different way to look at it that is less painful. I'm sorry that you get hurt so much.
