Wa Aleikum Salaam.
Sis, I think you need to see a counsellor, or a nurse or doctor.
I dont know if you are american ('cause you have to pay over there for medical care dont you?), but If you're in the uk, just go and see someone.
I understand a little how you feel.
I am, at the moment, about 70lbs overweight, and I vary between bingeing, and every so often restricting my intake severely.
It is true that starving, and that feeling of control can give you a high. You feel so accomplished, and so awake, that it can easily encourage you to continue, even if it hurts.
I also occasionally visit pro-ana websites, and yes, I can understand that "kick" you mentioned. They either inspire you, or cause you to feel so fat by comparison to everyone else there, that you immediately feel guilty about having eaten half a sandwich for lunch.
My Friend was bulimic and anorexic in school. Even after she recovered, she could still stick her fingers up under her ribcage. I guess it was her "party trick".
Sis, the results are not worth it at all... If you continue the way you are, your body will not be able to cope.
Health Risks/Consequences:
*Abnormally low heart rate and blood pressure indicating that the heart muscle has been affected by the self-starvation. Risk of heart failure increases as the heart rate and blood pressure continue to drop.
*Reduced bone density (osteoporosis) resulting in brittle bones, and in younger women (age 12-17), can affect bone growth and height.
*Muscle loss and weakness
*Severe dehydration which can result in kidney failure
*Fatigue, dizzy spells, fainting, poor concentration
*Dry, scaly skin and hair loss is common
*Growth of a downy layer of hair called lanugo all over the body, including the face, as the body attempts to compensate for the loss of insulating fat tissue
*Electrolyte imbalance
*Sudden death due to heart failure
