You've likely run into indexing issues because of bulk requests without proper setup. Submit a sitemap in GSC and configure your robots.txt.

BUt I have done a very hard work for them now removing them feel so hurt after removing and updating can I re index them?

You've probably run into ordering issues due to mass solicitations without appropriate arrangement.

If u have a lot of post in a short time it can be the problem
