Just dye it to some color that resembles your original hair color.

Do you prefer blonde or darker hair? Maybe you should go to a hairsalon and let them colour it dark brown to hide the colour you have right now. And then start to really take care of it. Let them cut the damaged hair. Always when you dry your hair use some spray or oil to protect hair endings. (Coconut oil is popular for it in Netherlands). If your hair is very damaged I do not recommend making your hair blonde as it would damage it more and you wouldn't get the right colour as your hair is orange right now. :)
