Post wedding blues

Hi,
Just wondered if other Mothers of the Groom have suffered with this, it is the name I have given to how I'm feeling. Having come home from my son's wedding 5 days ago, I am on the verge of tears all the time. It's not as if my son has just left home - he is 30 and has lived away from home for 3 years and with his girlfriend for 3 months. I was and still am, so happy for them, she is a lovely girl and they are well suited. After all, this is what we mothers want for our offspring isnt it?! I just wish this horrible tearfulness would go away!
