Since then my weight has been changing between 110-115 lbs. I thought ok I hate being this fat but it is better to live and be loved than be thin.

Resently I lost a little weight and it feels so good.
I'm now 5'4.5 and 100 lbs. I would like to be 88 lbs.
I really enjoy losing weight, it makes me happy.
I completly freek if I go over 105 lbs now.
I love to just run miles on the tred on a empty stomuch or till I nearly pass out.

I'm still with my guy and I love him but it just makes me happy. I hate to be fat.

I dunno if this is an eating disorder or not.
Just wanted some advice.

so chose:

130 lbs and living, or 88 lbs and dead.

hmmmmmmmm.....

I don't care about my size, I care about being healthy.  Being overweight or underweight are not good for the body.  There's a difference between being THIN and UNDERWEIGHT.

If you still can't control it, I would consider talking to a doctor.  I knew a female when I was younger who's doctor told her that her weight was so little (she wasn't anorexic, just low weight) that it could affect her growth.  Of course, you're older than that, so I suppose you're done with the growing... but it just goes to show that there ARE major concerns associated with body weights that are too low.  I would suggest talking to a doctor so that they can tell you what your ideal weight would be, and maybe they can help you figure out a diet that will give you the calories you need, but will keep you at a healthy weight.
