Best to just start eating regular, so long as you haven't put your body through too much hell and require medical assistance to rebalance the nutrients you've lost (which most likely is the case because 2+ weeks without food and only water is terrible on your system, electrolytes/sugars/essential vitamins/minerals are all probably extremely low).
Point being, starvation is never a valid form of weight loss and it'll shatter your health in the process even if you do manage to lose weight. Only way to really shed pounds is diet and exercise, and I know that sounds like a standard answer, but its damn true. Initially you may not lose a lot of weight with a proper diet/exercise regime, you might even pack a few pounds on at first. Muscle weighs more than fat (its more solid mass) so you may gain a few pounds at first while losing the fatty pounds. Really its fine though, its not the weight so much as the BMI you should be worried about.
It takes willpower and discipline, and it sucks if you're not used to sweating. I don't even mean going to a gym or jogging/running/bike riding. Simple exercises you can do at home, and a brisk walk around the neighborhood every day will do wonders for shedding weight. Then its also changing how you eat. Cut out the high sugar junk food, the empty calorie junk food (chips, soda, cake snacks/candy) and honestly find a nutritionist/dietician to help plan a meal schedule. If you don't know how to cook, now's the time to learn, because kitchen work makes you sweat. Toss your microwave in the trash (or just don't use it much if at all to cook) and start using the stove/oven to make food. Hell if you work and can't make time to cook daily, take a day off and make your weekly meals, freeze them and then you can use the microwave to thaw them for lunch/dinner. Breakfast though doesn't always have to be cooked, so you can save time there if that's a concern.
Anyway... whatever you do though, see a fuckin' doctor man. Suck up the bad feelings about getting scolded, because they're right, you're not and you need to hear it from a professional just how badly you screwed up. Doesn't mean there isn't hope, but you can't ignore it and expect it to go away either. You're most likely in a danger zone of health, and you really need a doctor's examination to evaluate whether or not you need further treatment.
No one here is being mean or nasty, but some are a bit righteously pissed off that you're taking such a chance with your health. Honestly that if anything should make you feel good someone you don't even know cares enough to be mad at you for gambling with your life. And you never know, seeing the doctor could reveal a condition like a thyroid problem that prevents weight loss and needs medication to balance the hormones so you can properly lose weight. You won't know if you don't go, and its not a smart idea to put it off any longer, especially, as I've said multiple times, when you're in a highly possible danger zone for your overall health.
Seriously, suck it up, go see a doc and be honest.
The future isn't dark, unless you refuse to walk out into the light my friend.
