how long does it take for birth control to be out of my system if i've only taken it 3 weeks?

i decided i'm done taking the pill because in the 3 weeks i've been on it, my moods have been so awful. all i do is cry and i've had several mental breakdowns and i haven't been this depressed in a while and before i was on the pill my mental health was doing so well. i would have some bad days just like everyone else but i was fine and actually felt happy which i haven't felt in years. i was SO proud of my progress and the pill made it all disappear so starting today, i'm done taking the pill. since i've only been on it 3 weeks, how fast will it be out of my system because i want it out asap!!!
