Binge Eating Disorder

So I just recently found out I have BED. I've always obsessed over body image and weight and was mentally abused as a kid by my grandmother telling me to always finish everything on my plate, but then if I wanted more or ate too fast, she'd call me fat and disgusting. I went on the Paleo diet about a year and a half ago and lost about 63 pounds (in a healthy way, not too quickly or by unhealthy means). I love my comparison pictures, but if I look at the second picture alone, I still feel like a whale. I was 5'7" and 157 at my lowest (second pic). Now I'm 167, not a big difference I know, but I feel like a disgrace. I HATE my body and don't look like the second picture anymore. I don't look like the first picture by any means, but I FEEL like it. I have no idea why I'm starting to hate my body again because just a few months ago I had an epiphany of "I love my body" and posted my happiness all over Facebook etc.. Then it seems the very next day was when my symptoms started. I ate a TON and felt like a complete piece of trash afterwards and it's been happening everyday for the past 2ish months. About a week or so ago I tried to throw up what I ate everyday, but I barely have a gag reflex, so it didn't really work and I got frustrated and tried to fast in a very unhealthy way. But my boyfriend started to notice everything and I told him all about what I've been going through. So we're going to work on it together. He is 500% supportive and I love him to pieces. I don't want to disappoint him and fail (Though he says he'd never be disappointed in me for failing 1,000 times let alone one). Does anyone have any similar story or tips for me to get back to the healthiest I can be? Thanks in advance 💕
