Hey there!
First off I want to say I am sorry to hear about all you have been through!
I understand it can be tough living through that. Things can and will get better though. Have you ever tried to talk to an adult about the bullying you've been through. A teacher, etc? You should not have to go through that.
I also can understand what it's like having parents who have marriage issues and end up divorcing. My parents divorced when I was young. Hopefully they will work with you so that you will be able to cope with it fairly well.
You can and will find happiness again! Don't lose hope on that. If you ever need anyone to talk to don't hesitate to
PM me. Your life is worth living!
