Is it normal to feel responsible for sister's disability?

That`s the saddest story I had ever heard. It`s normal that you feel that way, in that situation I`ll probably feel the same, but you should really get help because you can`t live your life with all those thoughs in mind.. It`s not your fault! Don`t blame yourself! Awww I wish you all the best, to you and your twin sister. Good luck, Take care :)♥
