This question is regarding toenail fungus, how to cure it? Ive never had fungus but all of a sudden I started ?

Noticing my big toe nails turn yellow I didnt think much of it so I would just clip off that area, soon my other toe nails had d same problem now my nails are horrible, I amashamed to wear sandals or heels, I have ogre nails they just grow up no nail bed, they lost their shape.Can I getthem back like new?? Any remedies?? Help plz.
