Heath Ledger?

ok i saw dark knight a few days ago and LOVED it. When i first heard Heath died it didnt seem real but when i saw dark knight it actually hit me that hes gone and i juss saw his last performance... and i still cry... am i the only one who feels this way i mean i feel weird cuz i didnt actually kno him personally but i still feel like i lost someone close to me.. i dont kno anymore and ive been really quiet which is weird for me... so am i the only one who still feels this way?
