Is this normal

So I have started eating bad. I’m at a healthy BMI of 18.9 but I went into a depression and stopped eating as much. And when I do eat it’s very unhealthy.

Before this I was drinking daily smoothies loaded with veggies and fruit and eating real foods. I never had any weird smells or sweated when I was eating like that.

Now, I’m sweating more and have noticed that my vagina gets funky faster and my armpits sweat way more and drink wayyy moooore even after showering.

Is this because of how I’m eating?
