Hardest day of my life

My daughter left on her trip today. We had so many things to do before going to the airport, it was just crazy! About half way to the airport the flood gates opened up. Of course I am a worrier and all the worst possible case scenarios were running through my head. Of course she was scared and so nervous, but she kept asking me if I was ok and telling me everything will be fine.
We got her all checked in; we went as far with her as the airport would allow us, hugged and said our goodbyes, I just wanted to run after her and tell her “SHE CAN’T GO!!!” I know she is a grown woman and I have to let go and let her fly. But it is just so hard! She will be landing in London shortly before noon then it will be off to her destination.
I so wanted to be at my baby girls wedding. It hurts, it hurts a lot. But what can you do?
With all these stresses I have been fighting the urge not to eat eat eat! I haven’t done much walking or exercising in this week. I will be bird sitting for my daughters 2 cockatiels (Junie and Ipyana) while she is gone for the month. They are missing her already!!!
