In general, 80 in a 50 would be 6 points or a short ban.
Speeding is a strict liability offence, but not an absolute offence (contrary to what some of our resident morons like to crow).
There are 2 elements to "proper" crimes - actus reus (the guilty act) and mens rea (intent). Strict liability offences do not require an intent, but if you were forced to do something (by threat or circumstances outside of your control), the defences of duress or duress of circumstances would negate the guilty act.
You state that you were "escaping" from a hotel, where these things "had" been done to you.
Duress defences are very time dependant - if you are, or believe that you are, in immediate danger, the defences are potentially available. However, once you get to a point where you are clearly no longer in immediate danger, they are not.
You mention having been drugged. If you were not thinking clearly because you were still under the effects of the drugs, that is potentially a defence.
If, at the time, you simply had a lot going on in your mind, then that is not a defence, and may or may not be effective mitigation depending on whether or not a bench would consider you ought to have been driving.
A person reacting to apparent danger is not judged by the standards of what a reasonable person with the benefit of hindsight would calmly determine to be the most appropriate course of action, but what a reasonable person in those circumstances might consider to be reasonable at the time.
