I wish I could make it all better, Lisa, but some families are unhappy and abusive. It's just the way it is and this sucks. You don't deserve this, no matter what you've done.
You've asked for my help....the one big piece of advice I have is to get an education. Stay in school. Complete your assignments. Ask your teachers for help. (Yes, they really do want to help.) And then when you've graduated, get out. Out of your biological family.
It sounds toxic.
You can't make your family stop yelling and arguing, but you can make a different life for yourself. It's hard when you want the people who raised you to be different and to love you. Sometimes, they just don't.

Good therapists are working their way out of their jobs.
In recent years, individuals have embraced the idea that brain chemistry can only be changed by taking antidepressants, anti-anxiety medication, anti-whatever pills. Many are convinced that they have a lifelong issue and will always need to be medicated.
Not necessarily true. Brain chemistry can be changed by the way you think. This isn't just a matter of thinking everything is okay, making it okay, but it means that you're in charge of your own life, even when it doesn't feel this way. It can be very difficult to deal with feelings and personal perceptions, but my job as a therapist is to help you find the tools to enable you to change your experience. I'm working my way out of a job.
I want you to prosper, to create the life you want. I believe that most individuals have the capacity to do this.
Learn to confront your own issues. Learn to believe in yourself.
