At the time of writing this, this manga has 19.4 chapters out. That's 19.4 chapters of literally no story progression at all. I even took a break with this one at chapter 16 and coming back to it, the story is still in the same place it was back then. It has potential, but the main issue is that the whole, "everything is hopeless, I don't know what to do with my life, woe is me" gimmick has overstayed its welcome by about 13 chapters. You only needed at max 6 to get the point across that the situation the mc finds herself is hopeless and she doesn't know what to do about it. At that point, you move the story forward even if only slightly. That has not happened yet, the only difference between chapter 19.4 and chapter 1 is the amount of information we have as readers, which is that she's stuck in a time loop and she has lost all hope of experiencing happiness. The pacing of the story really is abysmal, which sucks because the premise is interesting, and I'm a sucker for a pitiful main character who has lost everything.
