Congrats on the progress you've made so far. My concern, as someone who lost 85 lbs two years ago and is now in the next stage, is over keeping it off. You're certainly working very hard right now, and that's good, but how much of it is because you just got stared? You know how people like to refer to their diets as "lifestyle changes" instead of "a diet"? Well, that's actually a very important mental outlook that is meant to avoid the terribly unhealthy "yo-yoing" dieters experience of rapidly fluctuating in weight. I mention this because you seem to be taking a lot of steps toward your goal, but have you thought about how many you will still be doing in a month, six months, a year, 5 years? Cutting out soda is a great first step for anyone looking to lose weight, it was mine and the jumping off point for a whole lot more. Are you going to go back to drinking soda though when you lose the weight? Limiting sugar is always good, but is that style of rationing something you can live with long term? Working out is very important (though not as important, certainly not more important, as what you eat) but will you still be working out anywhere near as regularly this time next year? If you want this to last longer than Otakon 2014, you should be making changes you can live with the rest of your life.
Anyway, that aside you are doing all very good things. Counting calories can be very important, if that's your main dietary restriction. A word of warning on your numbers though, I used to try and hit 1350, but my own doctors have warned me not to go below 1500 a day. (I'm a 6' male, for reference) So something to consider or ask your own doctor about.
I am curious what your actual diet consists of. (The only things you specifically mentioned eating were chocolates and ice cream lol.) For me, I not only tracked calories but also tried to limit my carbohydrate intake to ~100g a day. What I'm eating currently (also while I was losing) is a sort of non-strict Paleo diet. No breads, pasta, rice, etc. Some dairy occasionally, and I don't have to be gluten crazy or anything.
I could go into why limiting carbs is important, but that might be more than you're looking for on an AMV forum. I highly recommend anyone who is seriously interested in the topic to read some of the research done by Gary Taubes. (this is a pretty good lecture: https://www.youtube.com/watch?v=M6vpFV6Wkl4
Paleo is the change that worked for me, and there are plenty of lifestyles to choose from that have worked for a lot of different people. I think the key is picking something that you can stick with.
