Hi Deafteen, have you tried shake awake, it's travelling vibrating alarm clock, small enough to fit the palm of your hand. It vibrates well enough to make you jump!
Does your sister hear the vibrating??
I can't understand why would it bother your sis as you used to have your mum to wake you up that surely would have woken her up aswell by her opening the door and walking into your bedroom that would have made more noise than your clock!!. You both are practically adults here not kids anymore!
My mum used to tell my brother tough and that I need my independance and a vibrating clock would help me wake me up. It's not our fault that we need it.
