Its times like this that the expression of words is a poor an inadequate substitute for what you really want to say but can't.
Setekh, you have been a valuable member of this community. You have helped people, shown more paitence than I ever could, shown us your amazing talents, and achieved a noble goal of helping create something larger than yourself. The reason that this place exists is through the hard work, determination, and vision of the people who started it and do not discount yourself among those who made it happen and gave it purpose and presence.
I think I speak for everyone in the community when I say that we will be sad to see you go, and even sadder at the bad news about your mom and the tough times ahead of you. Know that although some of us are thousands of kilometers away, in other countries and on other continents, we are thinking about you and your family.
Never give up hope.
