What should I do? I had a fight with my sister and it turned physical... then this happened
It's not good that the fight turned physical. How did that happen?
I've been single for a long time and I haven't been having my needs met.
You can be upset your needs aren't met. But don't resort to violence to attempt to solve problems.
I don't care about my sister anymore. She's a horrible person. I can't imagine why I even cared about her.
You being single is not an acceptable reason for you to get into a fight with your sister. Physical altercations with your family is wrong and should be avoided.
