How can I stop feeling like crap?

There are times where I feel like the whole world secretly hates me. I act like a wolf because I feel like I am one in a human's body and I just hate being restricted by people. I'm a dog on the leash. I feel like some people say they like me and they're my friends because they feel sorry for me. I'm socially awkward, I can't relate to people and I cause chaos a lot of the times. I wish I could just be left on an island, so I can be left to do whatever I wanna do with the silhouette spirits.
