OK, well this is starting to be much better news now.
There is a problem, but it’s not a long-standing one.
Up till September, you ate enough, but like most people the quality of what you ate was not good. The result was that, presumably pretty slowly, you added some fat weight. But you were at least taking in enough calories, assuming this recent dieting-down was your first such experience (???) and so if that’s the case, then indeed you weren’t hurting your growth up till this point in September.
Your choice of foods could have been better, your performance would have been better as a result, your body composition would have been better as a result, but no big deal: now you know one of the things NOT to do! 
However then in September you crashed off 20 lb, roughly, of weight in just three months. It is not the case, as seemed could be the case before, that you had been holding yourself down at around 110 for a long time. That is good.
But that rapid loss was not a good thing.
And it resulted in your recent extreme, sustained binge.
So it is fairer to say rather that your recent food choices have been characteristic of an eating disorder and your recent plan of how to respond to the consequences of the recent eating-disorder-type binging is also characteristic of an eating disorder, BUT long-term you haven’t suffered that.
That is good as it is far easier to get out of a trap just recently fallen into than one that has become ingrained.
If you undergo this severe dieting AGAIN then the consequence is extremely likely to be ridiculous binging AGAIN.
Your previous way-over-severe dieting probably depressed your metabolic rate severely. For this reason, it may have seemed to you that your maintenance is 1400 calories. But your maintenance when healthy is probably much more like the 3000 that you had previously been averaging.
The fact that you slowly added some fat at such intake doesn’t change the number much.
As for your water bloat, that does NOT take any severe dieting to get rid of.
If you’ve only gained a few lb of fat, that does NOT take any severe dieting to get rid of either.
Try 2000 calories for a short while and then after that, don’t look to limit how much you eat, but limit rather the poor choices in food.
And don’t go for weird macronutrient (protein, fat, carb) plans such as nearly-all-protein. At LEAST half of caloric intake should be other than protein. More typically at least 60%.
Your diet begun in September was also bad. Namely, “12 egg whites 1 yolk, multivitamin, water, tuna fish sandwich on whole wheat low carb bread packed with lettuce and light mayo, chicken breast and 3 servings of broccoli.”
Low-carb, OK. But extreme low fat at the same time? No.
There is almost no fat in that diet.
Everyone makes mistakes: the trick is to not repeat them!
