Hi there. I am a 17 year old boy and I struggle with anorexic feelings. Ever since I was little, I have always been a tiny, skinny little kid. People would always tell me how skinny I am. Although I did think I was fat, I didn't dwell too much on it. I am now in High School. A couple of months ago, I was walking around my house with my shirt off when my older brother came up to me and said "Wow. You're gaining weight; you need to start exercising more." What he said broke my heart. I know he wasn't trying to be mean, but ever since, I have gone off and on of eating, but I haven't been able to keep off food for longer than a couple of days.
However, I have only eaten about 50 calories a day for 4 days and I don't know what to do. I started out feeling excited to start losing weight but the situation has changed entirely. I feel so guilty when I lie to my parents by telling them "Oh, I've already eaten." or "My stomach isn't feeling good." I no longer truly laugh and smile, and my mind is constantly thinking about food. I know I haven't been not eating for long, but I can't seem to stop!
My parents don't know, and when I mentioned it to my mom one day, she started freaking out and saying that I was mentally sick, etc. I just told her I don't have that problem anymore, and that I'm over it. I love my parents, and I understand how they would be worried, but she really scared me. My parents also can't afford to send me to an institute, and I do not want to put them through that trouble. Is there a way I can stop this on my own?
I'm sorry for the HUGE description, I am just really worried. Thank you for being willing to help.
