My Depressed Love

Backstory

My name is Maki Nishikino and I have depression, for most of my life this hasn't affected me until I turned 15 years old going to high school as a first year. At home things we're terrible since my father has recently passed away , leaving my mother no other option but to move to Tokyo . my mom had found love and introduced me to her new lover , after a few months of working and unpacking . My mother and her boyfriend we're together to the point of they got married and my mom became a doctor and worked her way up to owning the hospital and that's when the depression kicked in. every time my mother had left for work he would always hurt me with out leaving a mark and I couldn't take it anymore. I decided to try ending it there but he caught me in the act and instead of trying to help me , he just insulted me , calling me a disappointment and saying things like " oh , I should had help you". I tried telling my mom what happens when she's gone but she never believes me until I had enough and I killed him when he decided to hurt me. I knew that my mother was going to freak out and call the police and so I waited , crying my eyes out and sitting next to the body like we was in a drama. As soon as mother came back and saw her husband on the ground and saw me next to him , she was scared of me and did what I predicted . When the authorities came , they sent me to the hospital and let me explain what happened and they believed me. After a few months of being in the hospital , I was able to see my mother again and she was sad because she never believed that he was abusing me when she was at work. And so she told me that she hired a emotional support friend for me so I can get better . I didn't like the idea and wanted to be alone until *knock knock* "excuse me , is this the Nishikino residence?" A woman said knocking at the door.

This is where my story begin.
