Trust me, your hair will not grow if you continuing straightening it.. as your ends when you straighten become damaged and will just keep breaking off no matter what 'miracle' product you use. Seriously I learned this lesson myself and I have the same type of hair as you. I actually hated my curls when I first went natural but honestly if you give your hair a little time to breathe without manipulating it it will grow... I wrote about my curly hair transformation on my blog you should have a read it could really help you xx
