Most people who haven't gone through it themselves will believe whole-heartedly that what you're enduring is "make believe". It's easy to judge what you don't understand and lay blame where ever you see fit. Your mom's doing that to you by not acknowledging what you're going through. Hell, the way she talks to you...well, lets just say that a mother should never call her child a ******. You just don't do that. It's like people don't understand that someone can just be ****ed up based on simply being truly unhappy. Just at their very core depressed, with no explanation. That has to be the worst for, at least to me. At least someone who's gone through bad **** can have an idea why they "aren't right". You don't seem to have that. You just are.
I don't have really any advice to give other than I hope you have someone looking out for you who isn't wrapped up in themselves.
