Pretty sure this same thing happened last time I went to Russia. I was stressing out about the trip before the trip, I went there, and I came back feeling absolutely stupid for having had been stressing out. As expected, the trip turned out to be wonderful - I was reminded about how great my family is, about how nice it is to come back to the city where I grew up, about how important it is to visit home. Nothing but good, positive emotions, great memories, and a pleasant feeling that I am still loved. This was an important trip, even just to remember that when I am feeling extremely nostalgic, I can always go back.
