Lockandkey04, I am sorry you are struggling with eating disorder (ED). Oftentimes a therapist specializing in ED will be helpful.
If you are looking for self help methods these are some that have helped me.
I have to watch what I eat because foods I eat can stabilize my moods or exaggerate them. A high protein low carb diet with snacks or meals every 3-4 hours will over time reduce my swings. I also avoid alcohol and recreational drugs because those can really increase depression.
Other lifestyle changes that help me are doing yoga, exercises, mindfulness, calm music, and being active on Psych Central.
