new! tribrunal on 28th dont know where to start

hi all
i dont know where to start so sorry if its a bit babbled

i fought my daughters DLA in april this year and won, it left me so exhaused and made my illness worse, so much so i actually put my DLA appeal to the back of my mind, untill 2 weeks ago when the hearing date dropped through my letter box

i knew my appeal was going to be harder to appeal against and i was supposed to seek help but i have left it to late, so i joined this site, im so confused by the site as well i wish i had found it before even trying to claim for mine, i do not know which peices of information to really look at as regards to the appeal

i have a bad back, doesnt sound painfull when i type it but it is, caused leg and saddle numbness which has led to some incontiness, also my legs are very weak especially my knee's and i do suffer some mental illness, all of which i take meds for, i work, now part time from full time and have had to be demoted due to this and have alterations done at work to enable me to stay, will this go against me? i have had 3 months off sick this year alone not all together, a few weeks here an there

i sent reports from a bupa doctor and an ocupational therypist, i have had an mri scan that did not show any spinal damage

im babbleing now can any one give me any last minute advice or tips, i knpw a bit of what to expect from my daughters appeal i just know that i will loose mine

thanks

thank you i now have a place to start
