Anxiety and depression question please...?

Hey, I'm 16 and a girl, they diagnosed me with "clinical depression" about 2 years ago or so. And anxiety disorder. I'm on an antidepressant and a sleeping pill (worrying so much I can't go to sleep) . I feel like my anxiety can get really bad it happens randomly sometimes. I start shaking and just feel really, well anxious or worried about whatever. I have and always had so much **** on my plate, you would not believe, but I'm not getting into all that. I guess it all just gets to me every now and again. But should I get on a pill for my anxiety? My only thing is I don't wanna be on a whole bunch of different meds. Also are their any "natural" things you can do when you start to have real bad anxiety? And also i was wondering if two go hand in hand? (Depression & anxiety) -so if my depression worsens does my anxiety as well?? Thank yal a bunch! (:
