Just getting started

My name is Christina and last summer, i was told that i was gaining weight by somebody I know. I got really worried and obsessed with exercise and calories. I went from 112 pounds to 96 pounds within six months and now, i am trying to slowly eat 100 more calories each week. This week, i'm boosting it from 1300 to 1400 calories and i'm hoping to get my period back as well. I'm 16 years old and i'm going to be 17 on June 11. I'm 5'2' and i weigh 96 pounds right now. I just joined this group to get some help and i hope that i can be healthy again soon. Thank you all for your support.
