Guys don't worry about it, every birthday is a shitty as the last one, that's what birthdays mean in the long run, another day of realising how truly alone you are.
I'm good, I'm well and truly used to it by now.
Life is what you make of it, and I'm still not where I need to be in order to change the pattern of things, but I'm getting there.
Meh! You´re NEVER alone, Berbs... I know you don´t believe in God, but you´ve got yourself, you got your kids, you got us... that´s something (and I do believe, God´s with you, too... even if you don´t) - they love you lots, you know that... and you love them, which is even more important.
And you are right - life to a point is, what we make of it.
And hey - I spent my last birthday in my robe, hanging out with you lot, too! AND I was ... old... and single... with NO kids... yet invited to a wedding at the same night - now THERE`S reason for depression, lol
