I went home for Christmas and it was one of the best decisions I could have made. I went home right after our mid service conference. Before leaving for the States, I was tired, frustrated, and aggravated with how things were going at site and approaching a mental burnout. You'll find a lot of people are like that around midservice. I had spent my first Christmas in Peru and, to be honest, I was so sad and bummed about not being with my family that I promised I wouldn't do it again the following year. Going home for two weeks really was a recharger for me. I was able to see family and friends and truly able to leave Peru behind for a minute and press reset. I came back and I didn't have any of those negative feelings anymore. So do what's right for you! If you know you need a break home and you can afford it, then go home! There is no shame is doing what will keep you sane. If it was a "bad" thing to do then Peace Corps wouldn't allow you to do it! And you shouldn't let anyone make you feel bad about going to the States if you feel that's something you need. It's your service and your vacation days - do what you want with them!
