How Do I Win To Get A Tpo At A Tpo Hearing?

My ex partner was arrested in oct2023 I had a TPO from his day of arrest that expired in December 2023 by feb 2024 he began to constantly sending letter, apologizing, telling me that I should b grateful that I still have my freedom bc he is locked behind bars(????this man shot me and put a gun to my head threatening to kill me and was charged with assault with a deadly weapon he’s only served 1yr n they have a parole date set for December 2026) the letters stopped back in may2024 but his siblings began to harass me and threaten me in public (approaching me in the store) since then up to now I have reported to the police in my county but they denied my TPO dude to lack of Evidence I have now refilled for a TPO extension (in the county the dv happened) against my ex submitted all letters he’s sent me as well as security camera footage of his sibling at my house but in the report they did not include those security footage only the letters that he sent, and have a hearing date do I need a lawyer to help me get this TPO extension approved? Why did I get a hearing date? What do I need to do in order for the TPO extension to be approved? I fear if they deny my TPO extension at court, he will call his siblings to hurt to me idk what else to do
