Why am I passing out?

You don't sound normal at all you sound sick. If you go back to starving yourself you will die, plain and simple, and i absolutely doubt you need to lose weight. You need to ******* eat! Hot dogs, burgers, fries, potatoes, peanut butter whatever. You should be eating about 1800 calories a day. I am pretty sure you are starving yourself you just don't know it. Again if you starve yourself you will die.
