"Usage of disabled toilet"

I get an infusion at PRI and the toilet in the department is too small for my needs, so I go next door in the Endoscopy department, who have said that patients can use their disabled toilet as it’s bigger. I have been chaperoned and shown by a health care assistant many times to the toilet, but today she was very busy so I went through there in the morning and everything was ok, even had a chat with the nurse in Endoscopy and I said that I would be through again later in the afternoon and she said that’s ok.

I went through there in the afternoon and was on my way to the toilet I use. I told the staff member I was going to use the disabled toilet and they walked towards me and said that’s not the toilet I can use, and told me to follow them to the one I could use. We went through a room of the corridor like a mess room/nurse lounge (that had a few seats in it, maybe a table in it as well). I was trying to keep up with the nurse whilst wheeling a stand with my infusion on it and holding my bag of supplies I need to take with me to the toilet to use all the time. They showed me the toilet in the corridor and the door I was to go out of. 

I felt I was back at school getting told off from the head teacher.

For me this was a very bad experience and will feel bad now using any disabled toilet in PRI.
