Tribunal in a few days

I'm getting really anxious now the tribunal is getting close, it's taken 9 months to get this far and I feel as though the pressure is becoming more and more. I've got severe OCD and depression, the OCD being one of the main contributers to my I'll health. I'm on 5 different medications ranging from antidepressants to sedatives to help me through each day.

I got 0 points for both components and I feel it is unfair. What is the best way to organise myself ready for the tribunal, my OCD makes my life hell, should I focus on the OCD for each activity? Like washing and bathing takes me up to an hour because of rituals, getting dressed becomes a lengthy affair because I get scared that people have tampered with my clothing, I don't eat anything that isn't in a packet because of paranoia it's been tampered with etc. also my OCD means I have to clean cutlery and plates again and again.

Has my OCD issue got enough weight behind it for the tribunal to see it for how harrowing it is for me on a daily basis, will I have state that I can't do most activities based on the huge length of time it takes me? This applies to every activity from eating to going to the toilet.... So what I'm asking is how is the best way to tackle the tribunal with OCD, just tell them the truth of how it's like for me day to day and hope they believe me?

I've sent nothing to the tribunal will this affect my chances even if I explain my disabilities? Ive given up a few times during this gruelling process and now I'm worn out.... Is it best that I go through my PIP2 form and write down explanations for each descriptor? Then take that sheet with me into the tribunal? Have people successfully gained PIP from OCD? Thanks Gordon.
