I initially applied for pip just after turning 17 for psychosis but I'm now nearly 20 and my life had drastically changed and I have since been diagnosed with autism.I did a change of circumstances to let pip know of the changes but it seems to me they are basing my claim on psychosis and seem to think I have Improved when that's not the case at all.I started a mandatory reconsideration but I don't think they will budge on their decision I would rather close my claim and start again.Can I do this?
