Dear Prudence,
I recently moved back across the country with my young daughter, where I hoped to spend more time with old friends. They are nice people but busy with their own lives, and I’ve only seen them very occasionally. As a working single mom, I don’t have too much time to make new friends—I’ve met some interesting people, but on the whole I’m pretty lonely. I try to focus on what I have control over to improve my life, and I know my old friends are not responsible for my happiness. But I get in a negative thought loop about how my life could be different if these friends had welcomed me back into their lives more. Can you give me a little objective perspective that could help me kick the negative thinking habit?
