Antidepressants!!😥

Ok so basically I've got depression and I've had it before and I feel that I'm at the stage of calm before the storm and I need out of this all before things start going even more down hill. I've heard that antidepressants are a good way to go about things if you've tried everything else (which I honestly have.) I was just wondering if anyone knew what age you have to be to get antidepressants. I'm 15 and really feel like they would help but don't want to go to the doctors if they're just going to turn me away.
