PIP appeal after tribunal

Hi. I failed my PIP tribunal, being allocated 4 points (7 on previous tribunal with same conditions). I was extremely stressed not having slept properly and felt very intimidated by having 6 people in the room (the usual panel, an observing judge, the clerk and a trainee clerk). I have terrible anxiety in that type of situation and struggle to express my thoughts and think of the relevant information so I don't feel I can represent myself well at all.  During the hearing I was told that we would only focuse on my situation as it was at the time of my application around summer 2018, yet I was questioned about some activities I started attending in the autumn. Also, they completly ignored what I said in my appeal letter about my difficulties going to unfamiliar places and kept asking me about my 2.5 mile journey to work.  They also ignored my difficulties with cooking, the fact that I often use a stool, need light weight pots and pans, and I don't cook as often as I'd like. I said I try to cook from fresh once a day. I support a couple of gentlemen with learning disabilities in their home  about 3 times a week and help them with their cooking which consists of ready meals in the microwave or oven so they focused on that instead of my own issues. They also completely ignored my budgeting issues and my anxiety about purchases of larger items (been living for years with broken furniture because of it despite having the money available).  I have requested a statement of reasons and the notes from the hearing which should arrive very soon.  Can anyone please help with the following?

1) Might any of the above points be considered errors in law?
2) How do I find a no win no fee solicitor in Surrey who could advise and also offer representation on upper tribunal? I have already googled as much as I possibly can.

Many thanks.
