It's never easy losing someone you love. Some people say it's worse if it's sudden, if they die tragically in a car crash, or have a heart attack young, or something like that. Personally I think it makes no difference. You've still been torn apart from that loved one. You still find yourself full of regrets. You suddenly think of all the things that you could have said, of all the issues that you left unresolved, of everything that you wish you could have done differently. It makes no difference whether or not you saw it coming. There will always be those 'what if's.
'What if I did this, or said that, or maybe if I was just a little bit sooner'. My favourite is 'what if I noticed that something was wrong.' Which leads to 'maybe I could have helped them.' That one always hurts the most, always keeps people up at night. 'What if I was able to save them?'
Like I said before, it makes no difference. You've still lost someone that you love. You can drive yourself crazy with the 'what ifs, I should of done this, I should have done that'. But you can't bring them back.
