T.S.
Aw, I KNOW!
My oldest, my only son, went to college in another state just a year ago.
I alone took him, got him all moved in, did the whole crazy Target-dorm-shopping thing, went to the parent-freshman orientation. We even spent a few days together before I left, seeing the Grand Canyon and a few other sights.
And even though I was sad (and saying that final goodbye was the hardest part, for both of us) I was just so freaking excited for him! Going to college, living in a dorm, it was just never an option for me. I was supporting myself right out of high school so being able to give my son this amazing opportunity is what made me feel the BEST.
Besides, technology has made everything SO much easier. We text/email a few times a week, and we skype as a family once a week, so you REALLY are able to stay in touch. Just give him a little space and time at first. I find that most of these kids, even the ones who LOVE being away from home, stay pretty well connected with their families.
Hang in there M., you'll be okay, and so will he <hugs>
