I never really had an ED until it hit at the age of 44. Growing up I had the thought process for it but was always too busy succeeding in life to allow anything to mess that up. Things like stress would always make me loose a lot of weight.....but the stress never lasted long enough for it to turn into anything....& my mother was always into dieting & I was chubby in grade school & promised myself that I would never let myself go the way my mother did.....& I rode my bike 15 miles to work & home & played racquettball with the other engineers I worked with & tournaments that I would end up beating most of them in.....exercise always made me feel good......so the foundation was there when I ended up loosing my career & realizing how horrible my marriage actually is.....& the pdoc gave me prozac which was a major weight loss med for me on top of the stress & the anxiety I was going through......& that hit starting at the age of 41.....ended up in an eating disorders treatment center at the age of 43......there were others there about my age......my problem was that I was so suidical during the time I was in the treatment center....that I really got nothing out of it & the therapist was trying to make me think things that weren't there in my thinking so I was totally angry on top of everything else........constantly in & out of the medical hospital with IV nutrition through a central line.
The thing is these days, there are so many people across the board age wise that suffer with ED's that in reality.....you would NOT be out of place given your age.....I am sure you would find many others in the same place & with the same feelings as you are things you are going through.

......best thing to do is give it a try......then you will know rather than assuming the worst
