I haven't finished it to tell you so...weeps.
There is this one where also two girls get isekai'd. I forgot if there is a pandemic she helps with but she's love by the spirits and the girl is her "friend" who belittles her (I forgot on purpose or not):

Well I forget the title so I need help ;-;;;,
The girl who is reincarnated as a someone who have healing powers, there are 2 but she was rejected they accept the other girl. Even though she is rejected she help in the pandemic and died in the end.
Thank you for answering!!!
