Please, someone help me i soo stresssed out!!!!!?

When I was younger I used to be a stick figure weighing only 90 pounds in middle school but I never ate nothing but three meals a day and It was all bad food never gained weight or anything. It wasn't until 9th grade I was overweight 5'10 229 pounds I got this way because all I would eat is pizza, junk food junk food and more junk food I would literally take in 5000 calories a day eating and eating with no acttivity playing video games all day! I was addicted to it and loved to eat! Recently I have turned my life around and am at 157 pounds 6'0 but I still love to eat, and with the fear of having my body go into starvation mode I eat 5 meals a day because I don't want to get fat again, the problem is I have been eating literally the same thing for every meal for the past 2 months. I weigh every thing before I eat on a scale and I workout everyday,my calorie intake is 2100 calories a day nothing but oatmeal for breakfast nuts,fruits and veggies and fish and boneless skinless hickey breast, it has gotten to the point where I haven't eaten a sugary snack in 3 months and I'm afraid of going out to eat with my family and friends in fear of weight gain and additives to food that restaurants have, truth is I missed being small,which I am now once again weighing 157 at 6'0 but I also miss eating normal things but I can't stop myself from eating healthy, I have a fear that if I don't eat every 2 or three hours my body will get deprived and I will go into starvation mode and gain weight but if i eat alot i will gain weight, im currently running a 5k every morning without a rest day in fear that i will gain weight if i eat breakfast without a metabolism boost ive been having the same breakfast everyday for the past 5 months oatmeal with either blueberries strawberries or blackberries and almonds with protein powder and skim milk which comes up to 738 calories which thats ok for breakfast buit i just want to be a KID again!!!!!! eat what my dad cooks for dinner instead of having what i have go out with friends go to the movies and have popcorn and candy but i just CANT!!!!! i dont want to go back to my old overweight self more importantly and cant even swallow a food that contains added sugar without getting extreme Anxiety! even organic cereals, if it is not natural sugar i will not eat it! why cant i just eat when im hungry and and stop when im full and just maintain my weight and not worry about going into starvation mode or any other Stupid crap! i just want to be normal again!Please, someone help me i soo stresssed out!!!!!?
You might have some kind of eating disorder, with the way you are thinking. Talk to a doctor or psychologist.Please, someone help me i soo stresssed out!!!!!?
With your level of activity, between the workouts and running you can easily take in 2000 to 2500 calories a day with no fear of gaining weight. If I were you I would eat 3 meals a day, keep the portion size reasonable and eat as healthy as you have been. So you are already doing many things right. Just stop stressing over gaining back the weight. Continue with your reasonable eating habits and exercise and you can occasionally go out with your friends and have some of that nasty junk food in small amounts. Personally I love the taste of a Burger King whopper, large frys and a strawberry milkshake. Enough calories, sugar and fat for a week! This I allow myself only once a year as a treat. I am 6' 1" and 185 lbs and intend to stay that way or even lighter. At 6 ft. and 157 lbs you are on the thin side of normal.
