I bet it was really stressful to go back home, see everyone, feel the love of your family, and then be missing Gemma and the BF and then leave to go back. That would be hard on anyone when you are living in another country. I know I have felt that "let down" when you look forward to something for so long and then its over and you have to go back to your regular life.
Just know that we are thinking of you and if you want to talk, I am here.
