SoDev, for Valentine's Day my son made me a card. That was very sweet. You will have many cards from Aaron to look forward to. And you will treasure each and every one.
I second Dandylion, you have NO idea what life will bring you in the years ahead. Keep your heart open to the possibility of happiness, so when the opportunity comes to grasp it, you don't turn away. I haven't gone through what you've gone through, but I often think back to the days when I was a child, when I was at my lowest. If I knew what was in my future back then, it would have been ecstatic.
