So recently I've started having weird body changes and I'm not sure what they're a result of. I've gained 4 kg very, very quickly and my skin has started to become very dry. I've been getting acne underneath my boobs, and a few on my face (this is weird for me because I've never gotten spots before) and I was wondering if anyone could give me any insight. I'm far past puberty at this point, and while my diet is poor it's always been poor and it hasn't ever had this kind of impact on my body. It's not because I'm coming up to my period either because it's been constant now for a few weeks
