Insomnia

I'm so tired.  The Brat is graduated and he's gone to the beach, and I can't sleep.  I just worry, and worry, and worry.  My medication isn't helping at all.  The graduation was wonderful and I'm so proud of him, but at times like this I can't help wondering about Angela.  Where she is, if she got to graduate high school...It goes on and on.  And it makes me feel disloyal somehow.  Am I bad mother?  I don't know.  I'm going to try and go for a walk today.  Maybe some exercise will help me sleep tonight.
