A unique story full of potential
After reading the first two chapters, I was struck by some things that prevented me from becoming invested in the story in spite of your writing being good and full of potential, and in spite of an emotionally rich and complex main character. So I have 3 pieces of advice that I hope will help you become an even better writer than you already are:
Read the story now
First of all, I feel as though I've been searching for a plot without being able to find one. I can't help but wonder why you being your story at the start of the first semester, then spend a few paragraphs in her home (which could as well have happened three years later) before skipping to the end of her BA. This is something that I've done (A LOT) and the advice I was given was to start the story where the story begins. Start with action, excitement. The reader needs to know what the story is in order to invest themselves in it and your characters.
Second, and somewhat connected to the first point, you rush the backstory a bit too much. Your MC, as mentioned, is really interesting and rich in emotions, but the reader needs to get to know her organically, with the plot. It's a really common advice to writers (that I've received so often and still don't always manage to follow) to "show rather than tell". The reader doesn't need to know everything about you character in the first chapter (in fact, they usually like the suspense), and what'll keep them reading is the story.
Third and lastly, you have very vivid descriptions of the surroundings, which is good. Your writing style flows easily and it's easy to get caught up. However, I feel like you cut yourself short, setting the scene only to move on to somewhere else. Or when you described the front lawn in Ch. 1., it felt as though some of the words you used were a little strange (a "huge" lawn, fx). It's actually really good writing, but a little more patience (or just editing) would make it beautiful.
