Hi, my name is DonnaBrown!

Hi Donna (I' m guessing) @DonnaBrown, and welcome to the community. Sorry we haven't got back to you sooner, but I am sure some of our more knowledgeable members will be in touch with you very soon. I have no doubt you'll get a great deal of help with this.
Though I don't know much about PIP or its appeal system myself, there are plenty here who do, and I would suggest you have a look at this link:
https://community.scope.org.uk/discussion/33548/how-to-appeal-a-pip-decision#latest
Let me know, if you can, if this helps, and keep in touch. Others will be wanting to talk with you soon.
Warmest best wishes to you,
Richard
