Merry Christmas

Also this year, Christmas is here.
Usually I don't like this day, but this year is different, I don't know why but today I feel happy, it should be because I received several messages from new and old friends for the season's greetings.
From about two months, I have deeply changed my lifestyle but not in a better way, I am more and more alone than before, I don't feel well, it seems that the others don't care about me, it seems I am invisible, nobody looks for me, nobody cares about me, nobody tries to understand why they don't see me anymore around as before.
All started during my last trip to London and to Dublin (from 26 October to 7 November), I don't know what, but somethings happened to me.
I need to change, I wish to become the same Alberto of past, but.. is it possibile?
