Help Me Fight My Neighbors Harassment: Legal Defense Needed

Help! I need a lawyer and I have no money to pay for one. My neighbor who has harrassed me so many different ways for so long is now threatening to sue me over a fraudulent claim that I am responsible for a supposed injury he had. He claims I moved my car to block him (he was trespassing in my driveway) and he couldn't stop his four wheeler mower in time and he hurt himself. It's another lie among so many he claims I have done. He has weaponized the police dept. against me, threatened to cut down my trees, trespassed in my yard and driveway, and harrassed me for four years. It just won't stop. I hate to ask for money but I cannot ignore it anymore. I need a lawyer. Please help me to fight back.
