I Feel Like a freak on this website...

I'm 18 years old, 5'9.5" and around 108-115 lbs and have always been very skinny. About a year ago, due to stress/health issues I accidentally dropped a few pounds, and before I knew it anorexia took a hold of me. I managed to get back up to the weight I was before but my BMI is still so low---As background, my family runs "long and lean". My father is 6'2" and 130 lbs, my mother is my height and around 15-20 lbs more than me (she was much lighter when she was my age). I don't starve myself; quite the opposite, I find myself eating 2500+ calories a day with little exercise other than walking, yoga, and the occasional run/light weight session. 

Yet on this website, I often see girls much heavier than me eating astonishingly less to maintain. I get such mixed signals---people saying I need to gain weight and am "undereating" when their meal plans equate to sometimes less than half of mine. I have found it extremely difficult to gain past this point and with my period resumed and energy levels stable, I wonder what it really is my body wants? My doctors express no concern about my weight, and actually never diagnosed me as anorexic though my loved ones and I know from the symptoms I was. However, a recent blood test revealed I had mild anemia. Basically, what should I do? I read startling posts about how BMIs less than 18.5 are dangerous and life-threatening and wonder what I'm doing wrong?
