Cant log in

The bug is that, the past year that ive played minecraft, everythings been fine and my account has saved on the launcher so i could play right away. But now today, I cant log in, i clearly remember my password and username, i got them written up even. It just says password is wrong, its not, I know it! Under accounts theres no account, not mine, no nothing. My friends had the same problem but they fixed it somehow, I did the same, reset my password, still doesnt work. Help me.
