i found this manga called "the blood princess, kill them all" and the art style is amazing, the premise grabbed my attention too, girl dies but death posseses her and now she's out seeking revenge on everyone who's ever wronged her, apparently the lead meets a girl later on and they fall in love, are there any other yuri manga similar to this?

We have a whole thread about manga recommendations you could've posted in, for the future.

To your question though, the Teapot Hero might be up your alley:

Very similar premise. Tragedy, revenge, gay (at some point hopefully)

there is also a manga/LN with same author and generic LN titles.

White Angels Have No Wings is a heavily vengeance-driven yuri story. Just be forewarned, it's quite a disturbing read at times.
