It hurts because it's a change. Everything you just knew is stirred up, all the routines are different. Everytime something happens between you and someone else, good or bad, you grow. You learn every day from people around you. SOmetimes that feels good sometimes it hurts. Experiences help us to grow and find out who we are. Apparently you are a sensitive person. That is great! It's very normal to feel frazzled and out of control. Imagine how it is for a married couple splitting up with kids and property and everything else. Don't lose sleep over it. Be resiliant and hang in there. Sensitivity is a wonderful quality to have, more people should aquire it. Good luck to you, I hope you smooth over these rocky times and have some more fun. It's summer, live it up!!!!!
