Chapter 11 spoilers:
Basically, it's mostly Mimika thinking to herself about how badly she wants to tell Yuzumori that she likes her romantically, but ultimately cannot because she doesn't want to ruin their current relationship. Mimika believes that Yuzumori's form of「好き」is different from hers, so she tries to calm herself down and not have any delusional thoughts about it.
Mimika thinks back to the memories they shared together and realizes that she definitely can't ruin their relationship because she would feel absolutely crushed if she said something that would stop them from being friends since Yuzumori is already so lonely... so eventually, Mimika answers Yuzumori by casually saying, "I really like you too, Yuzumori-san!" (not as a confession though).
HOWEVER, shit starts going down the drain when Mimika tries to shut her romantic feelings for Yuzumori away. Mimika, not wanting to let go of those feelings, breaks down because she is unable to move on. If I'm seeing this correctly, it looks like while crying, all Mimika managed to say out loud was:
Mimika: I like you... (just the typical「好き」, nothing too special... to Yuzumori, at least)
Mimika: ... Giving up is impossible. (Be aware Mimika doesn't explicitly say what she's giving up on)
Mimika: Simply remaining as just friends...
Mimika: I don't want that!
Mimika (to herself): It's over.
Mimika (to herself): I really went and did it.
Mimika (to herself): There's no turning back now. / There's no way we'll be able to go back to the way things were before.
Mimika (to herself): I have broken down. (Rough translation... I suppose she's basically just saying "RIP me")
EDIT: Forgot to mention that in the above, I believe what's implied is that Mimika's words can be taken as "I don't want us to be friends anymore", but it's entirely left up to interpretation. Actually, no, I don't know anymore, LOL. This is just what I think, but I could be entirely off the mark. Yuzumori might know what's going on.
