it was understandable at first but now its kinda annoying that she cries at everything. i want to see her standing strong not being a crybaby

it isn't that easy to change thought patterns. Talking from experience here. just because she is now suddenly thinner doesn't mean her personality suddenly changes. She still has her own way of thinking that IS insecure and anxious and that also won't change unless people around her will encourage her and show her that she has no reason to not feel so anxious. And it is not enough to have one person to tell you that, it takes multiple ones for you to actually see that it is not only an anomaly that you are seen as okay or normal.

I don't think her mental health progression is chapter-wise. I understand how it can get exhausting and emotionally draining to deal with a person who's constantly insecure and needs reassurance for every thing. And it's totally valid to not want people like that in your life because it takes its own emotional strength to support someone with deep-seated anxiety and insecurities. But at the same time it does not mean it's invalid that the person feels this way.
Like someone mentioned here it takes a while to unlearn negative and self-deprecating thoughts. But also it takes a different kind of strength to accept help from someone despite not wanting to be a burden. I'm glad that she has people to depend on. And you're right her progress shouldn't be for the sake of someone else romantic or otherwise. But considering therapy and professional help is not part of this equation as long as the ML is okay with it she can rely on him to grow.
maxi deserves everything good
