Is it normal to kill things when upset or hyper
I'm a 17 yr old female. I identify as an animal so for a long time I have always thought my urges to attack and kill things were normal. (Eg, wolves and foxes kill, but it's natural for them because they're predators)
But recently my urges have become more sinister. I used to just chase things down and kill them as quickly as possible and then take them home to eat. Now I'm just killing just to kill. I know it's wrong, but I don't feel it's wrong. I don't feel anything except for excitement and relief. I was abused horribly as a baby and toddler and was adopted at age 4, so that might be it, but I'm not sure. I feel like Satan is following me and just waiting to possess me. Sometimes I've lost control of my body and start going nuts by shaking and growling and salivating like a rabid dog. It truly feels like rabies. It's like all the pain builds up until I no longer am myself. Most of the time I just become aggressive and mindless and talk or sing to myself when this happens, but a few times I've maintained intelligence and have done things I'm not supposed to.
I'm just mainly concerned because lately I've lost my empathy. I've always hated people, but loved animals, yet still liked to chase them. Now I don't really care about them either. I'm scared and hurt and it feels like I'm dying. I'm terrified constantly (think scared bunny about to be disembowled by a hawk), and sometimes I'll spend hours hiding under the bed. I want someone to help me but I'm scared and my adoptive mom keeps telling me I just need to fix myself. I fight with her a lot because of this. I want help and her to be my mommy but she just gets mad when I try to tell her anything. Now it like im becoming a machine. I don't just want to kill, I want my victims to feel slow, agonizing, terrifying pain. I killed 1 bird today, 2 yesterday, and 3 the day before. I didn't waste them (I gave them to my dogs as a treat), but I know god probably isn't happy about it. I used to just be a predator, now I'm a killer. I didn't hate the birds, but it felt really good killing them. It doesn't feel wrong to me, but my adoptive mother and the bible have told me that it's wrong to kill for sport. I just need to know if they're right or if it's just a normal phase that upset people go through.
Please don't respond if you're not going to help. Thanks.
