Sugar and Rainbows

Used mostly in sarcasm.
means that even if you decide to do something, everything won't end up being all good again, nothing will change by what you decided to do.

You leave and everything will be Sugar and Rainbows?

Chasing the clouds/rainbows 

To go after something that you will never catch or pursue. Possibly something unreal, unrealistic, or impossible to get.

Unless you are chasing clouds away, in which case it means that you are clearing things up, making things better.

Running after you is like chasing the clouds/rainbows
