Everything was going pretty smoothly in my life.
My personal life or other aspects of it were good enough for others to be jealous. And it seems when you feel too much happiness in life some unexpected event may happen.

Three months ago my pet was diagnosed with incurable cancer and started to cough with pain and blood. Even though his eyes were telling me that everything will be okay, don't worry about me. Like he was comforting me.
But it was clear that he suffered and... after a while I decided to put him to sleep.
It's the most painful experience in my life. Holding him in my hands when his last light of life vanished.

Sorry @damarth for sad experience.
