lost 15lbs

last two years have been very hectic, moving to new city, have two different jobs, moving once in the city to a new apartment. going back to school, etc. my story just goes on and on of everything that i have needed to deal with. well i weighed myself tonight, because i own no scale and cant remember the last time i had a physical done(maybe two years ago to) i know realize being 5 feet 7inches tall used to weigh 140 pounds i have dropped down to 125. i am depressed shoken by the number, by the huge gap. my mom has always given me crap about how skinny i look, and i have always made the mistake of ignoring her. all the stress i have endured has caught up to me in this way. i eat like a man - lol - a lot bfest lunch and dinner + dessert, what is goin on that is causing all of this? i am calling my doctor tomorrow for an appointment because i am not anerxic(?) or belimic(?)
