Hayley, I can relate to you on a quite a few things.
1) I used to be bulimic
2) I was forced into therapy when I was 16 (not because of bulimia)
3) light headed ness, etc from lack of food
4) extreme excercise
it scares me to see what you are going through right now. No you shouldn't *have to go to a counselor if you do not want to, however whn I was 16 law took over my rights to choose if I wanted to go or not.- I don';t know if that applies where you live or not. I wish when I was forced to go I had taken advantage of the counsleing, becasue of issues i'm currently dealing with. I'm telling you right now, whether or not you choose to believe me- #1) laxatives do not make you lose fat, they just make you relieve yourself, causing the scale to register lower.
#2) if you starve yourself down to your desired weight, then begin to eat normal or bigger amounts of healthy food, guess what happens? Your body gains weight. It does this becasue you have starved it so long, that your stomach shrinks, your metabolism slows down, and tries to hold on to whatever food it can.
#3) when your metabolism slows down, you lose weight muuuuuch slower, then if you were to eat regular healthy portion sized meals- hence you starve yourself, your body actually begins to eat its muscle in turn, you lose muscle, so all the excercise you are doing in trying to build muscle tone your body whatever is actually being x'd out.
#4) if you were to eat 4-5-6 meals a day, healthy ones to start with 1200 calories- which is low, you'd lose weight healthier faster then you would by starvation, laxatives, orrr bulimia. I actually gained all my weight from bulimia believe it or not.
#5) if you go for long periods with out eating, say days or weeks months, and you introduce a solid becasue you are sooo hungry and deprived- the shock to your system from what you have done, may actually kill you.- your dizziness that you are experiencing from such low calories is actually lack of oxygen to your brain, which will make you moody, and confused and unable to focus.
I wish you would go to the counselor, I wish everything I just said gets through to you, becasue I have been through it too. Please keep us updated on how you are and try and be good to your body
