Love the responses so far - it is a mind game we play with ourselves. And I have my arsenal of tools with me now to defeat the obsessing...like Hopeworks mentions above. Books to read if I can't sleep are most helpful...just last night I had a bout with insomnia...read for an hour until I was sleepy again. Worked like a charm!
I have seen here often the quote: If you are going through hell, keep going.
So keep going, sweetteewalls. It will get better.
