Am I anorexic

I’m 30 years old and train and eat well and clean I rarely cheat

I recently broke up with my partner of 8 years and I drastically lost weight I’m still eating clean on most part and I’m training but less

Lately I’ve been getting very bad headaches and I’m anxious and feel stressed and nauseous I feel irritated at anything and everything I’m on my period so I know I’m not pregnant

I had my weigh in at the gym today and I weigh 48 kilograms

My body fat is 14% is that normal for a woman my age. I am 5 foot 6 tall :(
