I'm super sesitive to scents, too-- they give me headaches if they're strong enough. I won a Scentsy scent pack once and have been using it in a candle-heated wax warmer, and so far this year, I haven't had a headache from it ever. I think a key thing, though, is to identify what scents really mess with you and stay away from them in any form-- for me, floral scents and fakey scents like Fresh Linen or Sea Breeze always make my head hurt. Maybe try a more natural Scentsy scent that mimics essential oil scents (lavender, sandalwood), and see how that works for you.
