Arousal issue with vyvanse getting worse FAST! HELP!?

I'm 16(female) & have been taking my prescribed vyvanse for awhile now(little over a year), and while I've always noticed and tried to ignore the embarring/funny/terribly inconvenient side effect of being turned on almost all the time(which NO ONE WARNED ME ABOUT>:C) it's never really worried me. However, lately it's been getting progressively worse and harder to sate; it comes on so hard I can't function, and I'm slowly losing control of it. The REALLY scary thing is that I'm not ually active and never have been; the most I've ever done is masturbation (started at 15 when I promised myself I'd wait until 16...) and lately it hasn't been enough. I'm REALLY not ready for yet either(not trying it; 1:STDs 2:I figured out my mom was d at far too young an age, 4th grade, and that does bad stuff to you 3:teen abuse & divorse/breakup rates skyrocket here 4:pregnancy 5:trust issues from 2 and other stuff 6:social anxiety and 7: I'm very prone to depression) and I don't know what to do. I NEED some way to surpress it, push it back, stop it, ANYTHING. Just HELP!!D88)
