The guilt over eating and knowing how much i was eating, which contributed to my feelings of greediness, laziness and feeling fat, were hard to combat. It didn't go away in a day, each time someone around me worked out, each time someone around me mentioned that they worked out would cause me alot of guilt. Each time someone worked out it and mentioned it, it was like they had punched me in the gut and told me i was fat. That was exactly how it felt.... the guilt of knowing i was eating more but doing less was terrible. Fortunately for me, i didnt use Instagram during my recovery, it wasn't much of a thing back then and i wasn't really on the "fitspo" side of Tumblr so i wasnt constantly seeing workout pictures which was helpful for me. Because it was hard enough to get rid of an exercise addiction, to allow myself to rest without feeling guilty or lazy without having 101 pictures thrown at me of abs, squats, quotes and 10km runs.
It is tough to overcome the feeling of laziness, but know that you AREN'T lazy. You are strong, you are resting... your body needs rest to recover. And you know what... it takes strength to go against what the voice in your head is saying. If you enjoy working out, then it is easy to workout X days a week, but the strength is remembering that your body needs rest as well...that working out too much won't bring any positive benefits.

And when it comes to feeling greedy you need to remember that you aren't being greedy. The food you eat is for YOU and YOUR body. It is nourishing your body,it is fueling your body. I mean if you look at people eating do you think that they are greedy? Not really, because you know that they are eating for their body. However if someone orders lots of food and wont let you try a little or wont share a sip of their coke or a bite of an ice cream, that can be considered greedy... but then again not, if it is their food they have the right to it. Whether they want to share it or not is their choice and doesn't have to make them greedy. You are not greedy for eating alot, your body needs that food. If you were to buy lots of food, only eat a little and then throw it all away... that would be a little silly and almost more greedy than if you were to eat it all, though that is my opinion. When you realise that you are eating what is normal and healthy for your body, then it is easier to move away from the guilt feelings and feeling like you are greedy, because you arent. And you need to keep reminding yourself that until you no longer have those feelings.
And when you feel fat, try the things in the post below and see if they help:
Remember that fat isnt a feeling, it's not a bad thing. Get to the root of how you are feeling, what emotions is it? Is it stress, tiredness, anxiety, guilt? Because you can't feel fat (even though i know it feels like a feeling, but it isnt.) Know that your body doesnt change in the matter of a day or two, you can be bloated which can lead to "fat feelings" but there is something else causing those feelings and the bloating will pass, but you need to work with your thoughts and feelings to overcome those "fat feelings".
Change your negative thoughts, go against what the voice in your head says. Dont let the negative thoughts and words control you. You ARENT fat, lazy or greedy in recovery. You are strong for fighting against that voice in your head which is controlling you.
