As bridgey says, speak to your IP. Usually a break is offered ( which will be added on at the end ). Payments made to date might be another avenue, but would probably need you to demonstrate that you have been trying to find work.
Keep your IP in the picture, this won't be the first time he / she has had this to deal with.
My opinions are merely that .. opinions based on experience. Always seek professional advice.
