Am I developing an eating disorder?

In the past year I've healthily lost 60 lbs and my body is slowly starting to tone up. Just about 10/15lbs left and I'll be perfect. I do cardio where I burn 700/800 calories an hour at different intervals and then weight training (twists, plank, crunches, bicep curl, lat pulldown, squats, chest press, tricep dips and other tricep workouts) about 2/3 times a week and cardio about 4/5 times a week. I'm getting scared because I'm getting obsessed about losing this last bit of weight, extremely obsessed. I don't count calories but if something isn't super healthy (sandwich or something) I get super anxious. I'm so scared of getting fat again it's ridiculous, I'm scared I'm never going to get the body I. want. I never felt this way when I was in the process of losing the 60lbs, now I'm obsessed. Tips? I'm not counting calories because I know it will turn into an eating disorder. Tips please! When I look in the mirror I don't see how far I've come I always see how much further I have to go and I still don't like my body.
