That is tragic. 3 years ago I found my mum passed on the couch one Monday morning and my life drastically changed from that day forward. I used to think there is only one thing which could possibly hurt me more and that is losing a child. Nothing else will ever come close. I can't even imagine, I'm so sorry to hear this :(

Selling all my stuff, moving country, travelling, experiencing freedom for the first time really opened my eyes to the fact I was never depressed; I just had a really shitty lifestyle and no work/life balance.

It's unfortunate that sometimes it takes death to teach us to stop wasting our lives. I commend you for carrying on in strength. As you said, time heals all -- it is astounding what can be overcome through time.
