SCHEDULE 3 NOT MET BUT Dr CONFIRMING SYMPTOMS

hi i have received a letter today after my mandatory recon - i have been placed back in the support group from WRAG but only based on regulation 35. I am relieved to be in support group but very unhappy that schedule 3 decision stands. my Dr confirmed on the ESA113 that i have chronic pain, low mood, psychological problems, harmful alcohol use but yet schedule 3 was not met. I have spondyloses in my spine that is deteriorating, im under the chronic pain psychologist, have attempted suicide & suffer from OCD intusive thoughts, anxiety and depression.
It would not be possible for me to do any manual work & all my life was spent working at a desk doing business/administartion but now i cannot even raise my head, need a neck brace and my medication leaves me like a zombie. Is it worth appealing?? or should i just leave it and be happy im in the support group. I also asked for a copy of my medical assessment report several times but have still not recived it
