Yes, a lot has happened here too in all this time...
It doesn't matter! The main thing is that you're back and, even more importantly, that you're obviously feeling a little better. Fantastic!
Everyone else has already said everything else, so in short: keep taking good care of yourself and have fun!
it will take me a couple of weeks to get to know all that happened in here. The core did not change though - it's all about writing, interacting and, just like you said, having fun ;)
