Feeling homesick of Vietnam

How do you heal homesickness after a trip from Vietnam?

I was born and raised in the US and recently visited Vietnam with my partner. Both of us are feeling homesick and depressed that we’re back in the US. Our home in the US doesn’t feel the same. The bed doesn’t feel like our bed. The food doesn’t taste like home. The weather feels foreign here (California). Maybe it’s colder in the US that we’re losing vitamin D. We missed driving around town to pick a food stall on a scooter.

We have plans to fly back next year, but it doesn’t change our current situation now.

Both of us are struggling to feel home here again. How did you get by?
