I’ve had this mug for probably 20 years, it’s just one of those items that so well made and thoughtfully designed. The bottom brim keeps it steady next to me on the couch or bed, the handle has a little earlobe thing to rest on your middle finger so the actual hot mug doesn’t touch your skin, its big but not deep enough to make cleaning difficult and the hole on the handle is just small enough to keep a tea tag from falling through.
I won the brown cow mug in a contest where you had to collect yogurt container lids. For that brief time, I was quite addicted to brown cow yogurt, but mostly just wanted this mug. Even though it's a little chipped now, I still love it for my java indulgences. For non-Matcha teas, I often choose this mug I got from Minx Factory in Barcelona. I am a huge fan of theirs. I had a pastel mug previously but it broke when I moved back to Columbus from Chicago.
I've found the best cure for nostalgia is filling your time with new experiences, especially with good company. Maybe try seeking out some stuff that's outside of your regular comfort zone.
