Supporting my son into independence - help?

Hi I’m carer for my son. He’s 30 has Tourette syndrome with OCD, panic disorder, agoraphobia, sensory issues and hearing loss in one ear due to a tumour. So quite complex. We just a week ago moved him into his own apartment for the first time so huge step much to the surprise of his mental health team. It is a bit of a minefield though trying to do what’s needed to help him but not wanting to do anything that will take away the safety net of benefits I’ve fought to get him. He has a long way to go before he can be considered independent
