Warm hug book when feeling overwhelmed / lonely

Hi yall, I’m working full time right now (sometimes more) and spend every other free second I have working on medical school applications. I’m feeling pretty overwhelmed, lonely, and just tired. Want something to read that’s easy and can help bring some fun / light into this period of my life :) In the past, I’ve liked historical fiction (a thousand splendid suns, I am pilgrim, the great alone, where the crawdads sing) but I can’t get myself to read anything serious right now. Everything I have on my shelf is pretty serious and takes a lot of brain power, so need something light and fun to help me feel better!
