" It lacked the kind of structure and warmth of a community that I need. It was really isolating. I am looking for a student-centered school, ability to learn about my interests and discover my identity in a supportive environment full of excited and empowered individuals. "
This is not Gallatin. Yes, small classes. But suitable for a student who is highly self-directed and motivated and can navigate their own studies without a lot of hand-holding. I would not describe anything about NYU as a “supportive environment” vs. Sarah Lawrence (which is a MUCH easier environment to navigate than NYU). If the OP is finding Sarah Lawrence without warmth, welcome to NYC.
“At Sarah Lawrence, it was hard because I was able to do anything I wanted, but I had no idea how to grow because I didn’t receive helpful feedback on the ways I needed to improve, and there was so much freedom that there wasn’t a real focus in any of my projects.”
This doesn’t sound like Gallatin is the solution. Sounds more of the same, but in a huge university.
