Syag Lchochma – You’re welcome, and good for you for doing that. And I believe that if you are feeling lonely and you go visit a friend or relative or hug your kids, you are mekayem the mitzva of simchas Yom Tov the way it was intended, because you are relieving that loneliness – even if just a little bit.
AYC – The halachic basis for what I wrote about crying is here: http://he.wikisource.org/wiki/%D7%A2%D7%A8%D7%95%D7%9A_%D7%94%D7%A9%D7%95%D7%9C%D7%97%D7%9F_%D7%90%D7%95%D7%A8%D7%97_%D7%97%D7%99%D7%99%D7%9D_%D7%A8%D7%A4%D7%97 – s’if 5 and 6. The rest was not from a specific sefer. And you’re welcome 🙂
