>>11 It's your mother's responsibility to be an adult in these situations regardless of how you behave. You are a child. You're allowed to be upset at how you're treated. You're allowed to have fits. You're allowed to not be okay sometimes. It's supposed to be your parent's job to step up and get you the help you need,
especially when lashing out is the only way you can get them to notice you have a problem.
Your mother's also allowed to not be okay like any other human is, but for the years she's responsible for you, she needs to get that taken care of (so she can ensure your issues are worked out too, since she's the only one you're able to rely on). The fact that you're not getting any sort of counselling despite your behavior is a red flag that her mind is elsewhere. Does she have any physical ailments that are occupying her time/money right now?
I'm not saying to do anything now, but in the future, try to observe the people around you a little more. Point out your support beams. Be a little friendlier with the adults in your life and family. If it turns out that this isn't just a rough patch and it gets bad, talk to one of them or a school counselor, etc. and let them know that you honestly want a second opinion on what to do about your situation.
Never take, "put up with a toxic environment 'til you move out" as an answer, because that isn't one.
