Pain of losing something

Have you ever lost something that you really, really want?
How hard does it feel to to lose something like that?

Frankly, i've not lost much things in life that i really do treasure to that extent. But to those that i did lost, it was really painful, so painful that sometimes when i do think back, regardless how long it was ago, it would bring tears to my eyes.

Whenever you think about what had happen previously would you just feel so bad that... well you'll just get grumpy for no particular reason and you would just lose interest in whatever you are doing. Sometimes you would even blame yourself for what happened?

And how about love? What does it feels like to have your heart broken or even lose someone you like? What does it feels like to be unable to get the love of that special someone that you do love? I've personally have zero or little experience on this but i was wondering, does it feels similiar to what i've expressed previously?
