How do I get myself to tell my mom about my suspected eating disorder?

I suspect I have bulimia or an adjacent ED. I’m afraid to tell my mom and I don’t know why.

i think i have an eating disorder and ive been struggling with it for the past few weeks. not necessarily the disorder itself, im sure it started much longer ago, but just the realization and trying to process it and understand what im feeling.

i think it’s some form of bulimia. for as long as i can remember, really, i tend to overeat when no one is looking and then hate myself for it later. mom thinks i only ever want to eat healthy, and i do, but for the wrong reasons.

i did some research and i feel like i fit right into the basic cycle of binging and purging. apparently, purging means more than making yourself vomit, which i didn’t know until recently. it can include things like compulsive or excessive exercise too, which i do a LOT. i don’t workout for a month until i find myself having eaten a bunch of junk foods for like three days straight, and then suddenly i feel the need to workout for two hours straight and run six miles because i become incredibly insecure.

\[PLEASE CORRECT ME if any of this info is wrong, i did some research on my own but i may be mistaken.\]

I’m not sure if i’m afraid that she won’t believe me or something, but I just feel like this is going to be a tough conversation that i’m not ready to have yet.
