I am genuinely scared for my life now. My dog hates my guts and it’s giving my nightmares.

I rescued a puppy from my neighbours who were beating him daily. At first, he was very happy and listened to me. I would pick him up, touch his paws, take him for walks and he listened to me. After 6 months, I got him neutered and after that he gradually became aggressive towards me. It’s been 6 months to that and he has bitten me 5-6 times. Now he growls at me if I even look at him the wrong way. I am so scared of him that I can’t sleep at night. I get nightmares of him biting my face one day. I am afraid he might bit my parents or a visitor. My brother always played rough with him so he listens to him. But he’s leaving the country. In general I have seen he likes men more. People are giving options like leaving him in a jungle and tbh I never could imagine that. But giving the situation that looks my only option. Please help me. Is there any male who may already have another dog (he loves other dogs, never seen him hate one) and willing to take mine? I cannot afford months of training, I am broke myself. Please take my dog or I’ll just have to do something that I know will make me hate myself for life. But I cannot live in this fear. I need to sleep!!
