So it seems, Abbey , that you haven't been underpaid after all. Unfortunately there may be no big tax rebate to help boost your finances, so your focus now has to be on finding a full time job or a second part time job, and cutting back on spending including takeaways, nails, bottomless brunches and driving lessons for the forseeable future
Abbey, I think people here might be a bit more sympathetic if you hadn't been deceiving your mother (and yourself) for so long, AND you have ignored all the advice given to you months ago.
