what's the difference between better and more normal?

It depends on the context. BETTER refers to a feeling of wellbeing that comes from your body/illness healing. MORE NORMAL would apply to a woman who is undergoing chemotherapy and gets a wig in order to feel more normal in public when her hair falls out. Otherwise, more normal can refer to feeling more like you normally feel when you’re not sick.

тогда Более-менее нормально будет ок
