Provided you're healthy, then I would find that height/weight attractive, sure. Given that you said you've tried everything, it doesn't sound like an eating disorder, or anything.
I've dated girls around your size, before, and was always attracted to them. Some guys like short, skinny girls, and some do not. I just happen to be one that does.

meh I'm about 5ft and 95lbs so fairly similar to you, yeah some guys find skinny petite girls unattractive but there are also tons of guys that find it sexy as hell. Don't change yourself, you just need to find the right guys for you
