Do i have symptoms of anorexia?

I'm starting to come to the realization that I just might have a problem on my hands. I'm 16, 5'8 and 116 pounds. A few days ago I was as low as 114 but my family took me to a nutritionist, not for anorexia, but for my dramatic weight loss (34 lbs short period of time) & digestive issues. I'm trying to keep it hidden but I keep seeing things online and how i match all of the symptoms. I've missed my menstrual cycle for a few months now, headaches, i'm always cold, & have severe constipation. Food makes me anxious & I count calories like crazy. My aunt had suffered from this when she was my age as well. If theres anyone who can shed any insight I would really appriciate it. God bless<3.
