Numa - welcome!! You have been going thru a really hard time you poor thing. My deepest sympathies on your Dad and Grandmother, I am sure you are heartbroken. That in itself is so hard to go thru without doing IVF as well...
I am so sorry about your failed IVF cycle - it is so hard to deal with after going thru all the needles, stress etc. My first cycle also failed. Am also sure after being told you had 19 eggs - an amazing number by the way, that none were successful, you just didnt know what to think.
I also have ICSI because as you get older your eggs get harder and makes it much more difficult for the sperm to enter on its own. With ICSI - that actually put the little swimmer into the egg so he doesnt have to break thru the wall - so to speak.
I am sure it will help you when you are ready to go for the next round.
Stay positive and dont give up...
