First Tier Tribunal from hell today

The Judge today wouldn't let me speak and dismissed UC regulations re income from lodgers and capital disregards and the Advice for Decision Makers Guide. He was only interested in UC Regs 2013 which doesn't specifically mention lodgers. He adjourned hearing to request attendance of DWP PO and a breakdown of how my overpayment was reached. He wants another full day hearing. Given my mental health and mobility problems, I don't think I can tolerate anymore sitting for hours and im thinking of withdrawing my appeal. Any advice or thoughts would be welcome 🙏
