I remember your previous threads, as well, and I think it’s very important that you accept that she is not interested in you romantically. She is trying to be nice about it, though, by saying she’s just not interested in dating. That is her trying to let you down easy without hurting your feelings, but if someone comes along that she is truly interested in dating, be prepared for her to start dating him.

I am telling you this because I want you to realize that you blocking her for your own self-care is not going to affect whether or not she dates or gets close someone else in the future. That is likely going to happen regardless of what you do, but you will probably feel less pain when she does if you take the time to detach from her some. So I would just explain to her that you need time apart, then block her on all outlets and don’t talk to her for a while, at least until you are able to stop thinking about her all the time, are feeling better, and have accepted that she is not interested.
