Being sick sucks. What is school but chaos when it begins or you return? Depression is... well... the world is never as dark as it seems. Keep going. Lean on those around you. Friends and family should (I wanna say 'will', but... people be people) understand the inconveniences, hurt, outbursts, etc., come from you hurting, not just from you. Doesn't mean it won't take time to heal, but the healing should begin sooner.
Selfish? Meh. You needed time, and you took the time you needed. You're back now, and life is... calmer? More organized? bleh... not my life to say on. Granted, this comes from me, someone who has taken 4-6 month breaks with absolutely no warning beforehand. Sooo... yeah. :P
As of 2-ish weeks ago, Iktomi (and you, but... meh) was the only person who hadn't responded to pinglist. Darkstar, Jorik, and new to me but FantasyChic have dropped or been gone forever. Your call to remove them from the pinglist.
Also.
