Help? Do I have an ED and not know it?

Hi guys, my first time posting to anything even remotely to this related so I'm rather unsure where to start. I'm a 22 years old and have been diagonsed with with various things such as MDP, Post-Traumatic Stress Disorder, intense Generalised Anxiety Disorder and Typle II Bi-Polar since the age of 12 with various issues caused by a traumatic childhood before that. Not to sound extreme and attention-seeking but basically what I'm saying is an Eating Disorder is the last thing I need.

I didn't think I have a problem, however the increasing amount of "concerned" comments about my weight loss and "how skinny" I look (though I see myself as someone on the bigger side of average) is starting to worry me. When I look at the rare figure I can see that at 165cm (5'5") I've gone from my highest weight at 98kg (216lb) in early-2008 to 57kg(125lb) I can see how that is a pretty extreme change but I like the way I look now so much more, I feel a lot more confident body-wise and I feel healthier and more active than before. However, the fear that I will gain this weight back is quite terrifying and the desire to continue to lose weight or at least somehow maintain this weight is something I probably think too often about. I feel that I eat the exact amount I actually crave and never consciously force myself to go hungry unless I feel too wretched to eat.

I've gone for a blood test to see if I have a problem with my thyroids that caused this weight loss (I have a struggle believing I lost this weight all myself) which I find the results of in the next few days, so maybe I jumped the gun posting here, but I don't know... I just want to know what in the hell is going on with me.
