I just ask that any advice be quite specific, as I don't want to make mistakes in this process.....
Specifically, at this stage, you need to attend court early and speak with the prosecutor.
It may be surprising to some but ultimately they are not there to try and catch you out and generally will be helpful.
They do have a job to do of course, which is to prosecute offences, but this does not mean that they do not have a wider remit of being public servants.
Also, although on here these things are often shorthanded to doing a 'deal', it is not really a matter of being some sort of deal but rather a matter of CPS policy.
Go along and see what happens, you can always change your plea if appropriate.
