Ok thanks for the further information.
The court on Tuesday will firstly look to punish you for the no insurance which is usually 6 penalty points and a fine. The fine is based on your weekly income.
Once you reach 12pp or more the law says that the court must ban you from driving for 6 months. There is some discretion however if the ban would cause exceptional hardship.
That is what is sounds like exceptional circumstances that would mean that losing your licence would have a serious impact on your life. It needs generally to be more than just the loss of a job, it would have to jeopardise your home and maybe impact on family/ friends too.
Sometimes the court will deal with this at the first hearing but sometimes they will adjourn the case to hear the exceptional hardship argument at a later date. If they do, you will still be able to drive until the next hearing.
You can represent yourself at this hearing. If you do then you ideally should take papers such as a letter from your employer which says you cannot work without driving. It might be too short notice for that.
You can get a solicitor or barrister to represent you at the hearing on Tuesday. Even though it is short notice, someone will likely be available. You can find a local solicitor here: https://solicitors.lawsociety.org.uk.
If you really can't find one and you want one then ask the court on Tuesday for an adjournment. You can also ask for an adjournment if you need time to get a letter from your employer etc.
