PIP

You don't need to say that you cannot stand anyone helping you. They do not need to know that. Just say that you need support. That not everyone can help, but the right person could. (even if you don't know who that is yet!) You don't have to have anyone, just the need for someone. They could help by reassuring you that the person is cleaner than you think perhaps and by calming you down.
Years ago, I said that I couldn't have anyone indoors to help me and so they stopped my money because I could not accept help! If you say you don't go out at all, then you won't get mobility.
It's not like you will be forced to have someone help you, by saying that you need someone. Just the fact that you need someone will get you the PIP. Hope I am making sense.
