You received very good advice from Paxiled. That is still a very low dose, and you should not expect anything worse, but to get better over about another week....
You should never quit a benzo cold turkey! You need to taper slowly and under the care of a psychiatrist. You seem to be okay, but they can cause seizures and other serious problems upon sudden stoppage. As to how long withdrawal lasts, that depends on the person. It's not a one size fits all situation. Can be easy, can be terrible, can be very quick, can be very long.
