RIP, Paul Walker and his friend that passed with him in the accident. Paul Walker was such a great actor, and I know he must've been a great companion to those who personally knew him. You will truly be missed.
Not all Slytherins are evil, nor all Hufflepuffs weak. There are caring, fiery Ravenclaws and twisted, cowardly Gryffindors. Your house is not who you are, it's what you value. Your house does not define you. You get to define yourself.
Harry Potter was saved by a mother's love more than once. Harry may not of had his mother but he had a lot of comfort from mother like figures. Whenever Harry needed comfort it was always from a mother figure.
