I don’t know if I’m in the wrong???

Okay so I love junk food, I don’t put on weight super easily. This week I’ve been severely depressed. I’m fighting a constant battle with my appearance and weight. I’m approximately 8 stone. So I’ll have a bit (a lot) 😂 of chocolate everyday. I was eating chocolate tonight and I took maybe 4 smallish pieces. I then went to get more and my mom was laughing and was like “No you have like.. 4 pieces”. I want to point out that my mom is a heavy women and she eats worse than I do, she’ll just keep eating crap like chocolate.. Sweets thought out the day. I was extremely hurt by the comment she made because I’m just going through some weird phase right now. I just don’t like her making comments when she knows she does this too. It’s like, how can you say that to someone when you’re constantly eating the way you are? I kinda just sat in silence, we weren’t talking at all and she just went to bed. I refuse to talk to her about how I’m feeling, she really judges me when I do. She always says that I shouldn’t be down about things because I’m only 21.. Makes no sense to me. These past couple days I’ve been good and have only been eating when I’m hungry. Usually I’d have some sort of sugary snack in between each meal. I don’t know if I have a binge eating disorder.
