He's not a whiny psycho. He just feels that he can and should be able to do anything, being the Chosen One and all. If he's suppose to be this all powerful Jedi, why can't he keep things the way they are?
Life doesn't work that way. Things always change. For Anakin, it comes from a place of love but because he's a Jedi, he can't have these thoughts. Trying to figure out how to make everything and everyone around stay the same and keep things is a pathway to gain more power...and for a Jedi, that's the Darkside.
