Welcome to the community.
If your current housing provider is unable or unwilling to rehouse you somewhere more appropriate to your needs you may need to deal direct with the local authority. Have you been able to submit formal evidence (such as a report from an Occupational Therapist) to the local authority Housing Officer, showing that your current housing is not fit to meet your needs?
