I have a sister who uses the law to her advantage making up things to make people who obey the law seem like they've done wrong. I have no police record but she has a big history that has gotten alot worse in recent. She has recently been diagnosed schizophrenia and bipolar and stopped taking her medication within 4 weeks of been diagnosed. She got mad when we saw her out and wouldn't talk to her and started texting till i had to block her. She and her husband have violent records and I fear for me and my family. She wouldnt threaten because she knows she would be arrested. What are my chances of a restraining order?
