Thank you for the kind words and suggestions. I spent the evening packing for Thailand (we're headed off this afternoon), petting my dog and working on tricks with her, and drinking flavored sparkling water which is one of my favorite treats. (Sometimes I'll chill it and pour it into a champagne glass to make it feel more classy and fancy).
It's easier to deal with loneliness when one is busy. When we get back from our trip, I think I might start looking for some volunteer experiences. Things that can help me to feel gratitude for what I do have, and get myself outside my own head.
And my dog. Best friend in the world. She is my #1 reason for being alive. Pets are so, so important.
I'll be stateside again in two weeks and will let everyone know how it's going.
