Hey, Pizza Express deliver? Excellent news!
The only problem with that is that a motorbike throttle works in the opposite direction to that of a helicopter. Can be confusing.
Seriously, you better take yourself back to to school and get some more hours under supervision if you want to work as a commercial pilot. The key here, I would think, would be admitting your errors and proving that you want to work to correct them.
The industry is very close-knit and I'm sure word gets round so, unless you work very hard, I would suspect that your chances are the square-root of diddly-squat. Perhaps have a chat with your Chief Pilot/Instructor; what are their views. They should also consider your total hours, how well you get on with students and how well they appear to be learning etc etc. But it doesn't sound good.
Cheers
