When bullying doesn't stop

To make a long story short: I was bullied in all schools I've ever went to (since age of 7 till age of 18). In university there was a break, which I used to publish a book and move abroad. When I did, my old friends cut contact with me and some became my haters. They used fake accounts to write me offensive, demeaning reviews. Even though I asked them to stop and told them I would go legal, they kept doing the same thing. I have found a way to solve this problem, but... but what about the way that it makes me feel?

I have learned my lessons about self love, I know that I deserve to be treated with respect and that I don't need to put up with such behavior. I can be assertive when I need, I can stand up for myself and my close people. This summer I got hit in the head by a neighbour who threatened to kill my dog and called my mother offensive names. I went to the police to sue him. He got scared and stopped bothering my family. However, I was so anxious and stressed. Now I feel the same. The people scare me, really. I know that the people can do anything. And this internet hatred from my ex friends feels like a thousand knives being pushed deeper in my body.

I have no idea how to protect myself emotionally. As for forgiveness - it might be useful when the problems was solved and you are still stuck with anger. However when you are continously under attack, forgiveness shows the other person that they can do whatever they want to you without any consequences. So don't tell me please that forgiveness will solve all my problems, because it won't.

What can I do to feel better about myself, to stay strong emotionally, when there is always someone or something against me? I have done lists of my skills, my supportive people, how the universe is for me etc. But I still feel so miserable when I encounter new hatred. And hatred is everywhere. I feel like I am walking under a rainy cloud. Can somebody help me?
