Mother issues.

My grandmother is almost the same way. I wish I had some advice to give you, but all we do is humor her to the point that she finishes and walks away. . . Nobody wants to actually broach the subject of any possible disorders with her, and we all feel that with how tough of a life she had, she deserves the oppertunity to give it back.
Does your father work a job where he's away for long periods of time? We think my grandma is crazy because he would work out of country for months at a time.

 

Your mom reminds me of mine. She would get extremely upset over small things, like, for example, me not being able to find something in the refrigerator. She would find some way to insult me in a small way on an almost daily basis. And if I ever dared talk back to her...well I only dared do it twice. The first time, she told me to get out of the house, but then changed her mind before I got out the door and instead settled on throwing a temper tantrum. The second time, I got out of there before she had a chance to stop me. Apparently she was diagnosed with bipolar disorder as a teen, but hasn't sought any sort of help for it in almost 30 years.

I decided to just take it and wait until I was old enough to get out of the house. (I only went back for the summer this year because I was too cheap to rent a place for the summer, though I will never make that mistake again.) In the meantime, you can try to do what you can to improve things on your end. For instance, if you haven't cleaned your room recently, then maybe pick some things up. Even if she is overreacting, that should help pacify her and keep conflict at a minimum. You can try talking to her, but be very careful. Since you're not old enough to live on your own, it would not be good if you got kicked out now.

Also, is there any hope of getting help from your dad? I thought I'd managed to burn my bridges with my dad and his wife, but was pleasantly surprised to find that they were happy to take me for the summer. I'm not saying that it will necessarily work out in your case, but it's always good to have a fall back plan.

 

Im also in a wimilar situation, my mom is diagnosed with depression and bipolar, ontop o that she is also currently going through a divorce with my dad that has her stressed emOtionally physically and mentally. Im trying to get a job and save up so I can move out by the time i am 16 aswell (*hug*)

 

Just a disclaimer/background, I have had far from an easy time with my family in the past. However, truthfully I would not say that I recommend people to move out of their house before they have a comfortable way out(College, another family member, etc) because especially being younger than 18, it would be quite difficult to manage a job, school, house, bills, etc. Some oppertunities wouldnt even be available people who are underaged. Now, there are some places around the world where it is alot easier to move out early, I'm just saying that you should really put the time and thoughts into knowing that you have solid plans before doing anything drastic.

I know people can be extremely difficult, but you have to really slow down and make sure that you are choosing the most resposible decisions that will benefit you most in the future. Not just a hasty emotion-driven decision that will give you momentary enjoyment in the presense.
