I can

At the beginning of quarantine, I decided that I would use the time stuck at home to get healthy and to treat my body right. I started working out almost every day and started eating mostly plant-based and vegan although I was not on a specific diet, just eating healthy foods. I was eating probably about 1200 calories a day, sometimes probably a little less sometimes a little more, but was under 1500 every day. I'm not really sure when I started to binge eat, but it has probably been at least a month or two at this point. It always starts with eating one thing like a piece of chocolate or something and then I want more and more and more. Then I will continue to eat until my stomach hurts so bad that all I can do is lay down and barely move. I have attempted purging a few times but most of the time I just lay there in pain from being so full. It makes me feel so gross and guilty and I'm gaining back all the weight that I had worked so hard to lose. I don't know what to do.
