Can you please pretend to be a psychiatrist? 

I did a bad thing this evening. I see something that made me very mad on my computer and I reacted poorly. I took my anger out against my two dogs, a geriatric female pug and an old male beagle. I kicked my pug and screamed at my beagle. I flip every chair I could find in my kitchen and dinning room. I feel really bad now. I punched myself in the head afterwards out of guilt. My parents and sister are angry at me. I'm thinking of running away or harming myself. What should I do?
