Hey hon, welcome.
I'm so sorry you're feeling like this. My daughter is 14, I would be devastated to find out she was feeling badly.
Are you and your Mom normally close? Is there anything going on in your lives, or her life, like a recent move, break-up, divorce, loss of job? What's going on with your brother? Why is she afraid of him, and how old is he? How about you? Do you go out socially? How are your grades? Do you get into trouble, at home or at school often?
If you can elaborate a bit, we'll try to figure something out together. Always know you can reach out to any trusted adult in your life, when you're feeling badly. If it isn't your Mom right now, then talk to your guidance counselor at school, someone at church, a neighbor, aunt, uncle, someone. Of course this is a good place to talk and vent also, but reaching out in real life is always more important than reaching out online...for the bulk of your support.
I would normally recommend sitting your momm down, when it's just the two of you, and tell her, heart-to-heart how you're feeling, but I'm not sure what's going on with your Mom and if that's a good idea right now. It sounds like your Mom has her own issues she needs to address, either with depression, anxiety, or just life stresses, like when it comes to your brother. Sounds like she is just taking her anger out on others, namely you. So, hold off on the heart to heart right now....as you don't want to make things worse. Start thinking about another adult you could confide in for now.
Please come back and share with us some more information, whatever you're comfortable sharing, so we can get a better picture of what's going on. Remember, the way an adult acts or behaves is NEVER your fault. Your Mom sounds like she's taking things out on you, and that's just NOT okay. We'll figure something out. Glad you found us, sweetie.
So sorry this is happening to you.I recently got some bad news about my heart only to discover the news wasn't as bad as first expected.Are there hobbies you can do to take yourself out of this situation?Do the things that make you happy,thats what I am doing now and I feel better,I try my best to stay away from negative people but it's hard when their your family.Maybe wait for NurseGirl to come online with some better advice or some of the other good people on here.I wish you all the best.
