Adult lady who has been bullyied by nephew, who shares cottage ownership

The family cottage that my parents bought in 1948 was handed down to me & my sister about 21 years ago. My sister never used it but her son & I shared it for the last 20 years, without fighting. In 1999 my sister told me & her son to start sharing the cottage expenses. My nephew would never settle up the costs, since then. He pays for maintenance of the cottage & cutting the grass & I have paid for all the taxes & hydro. He bullied his parents into giving him the cottage in 2002 & has been harassing me since. I have had to call the police and I paid 50% of the costs for a new dock for both of us & he bought the lot next door & put the dock in front of his empty lot. At a later date he told me that I was trespassing & should remove my boat from the dock. That is when I called the police. For the last 2 years I have had so where to park my boat expect out in the water in front of the cottage. I have had little use of the boat because the waves pulled it in to the shore & it was grounded twice in the sand. I am now suing him in small claims court for $9500. & the value of the cottage goes up $30,000. per year. I am afraid to go to the cottage when he is there, so I try to rely on friends coming with me Monday to Thursday night, when he is not there. He stalks me in the cottage & tries to back me into a corner of my bedroom. I have used a lawyer to no avail. Can anyone help me?
