Mirena making me CRAZY

Lauren • I hope you have toilet paper ; because shit is about to get real.
I had the mirena on the 22? I want to say ..
I've been moody and slightly depressed...is this normal ? I don't want to rip this thing out , it's amazing I don't have to take a pill for 5 years !
But will the craziness last?
Side note : I haven't been on a pill for 6 months prior 
Will my body get used to it ?
