Yes, you will need exercise and sleep as so many threads suggest. But in your current state, just seeing the laundry list of things you need to do, yet knowing you just can't find the motivation to stick to any of this will just push you back further. The number one thing you need to do is think of one person, just one person, who has supported you unconditionally in the past. They should be someone who can give you a positive outlook, someone who could buoy you up. Talk to him/her to vent out your feelings. If you can't find such a person or if this exercise does not help, meet a professional. Once you are a little bit on the road to recovery, incorporate exercise. That will automatically regulate your sleep and push you towards healthy eating without much effort on your part. Exercise regulates your hunger and craving for sugar. The positive cycle will build on itself. Just take it slow. First, just talk to a trusted person, hopefully a friend who has seen you at your best. They can help bring out that person in you.
