my mom told me to end myself so i will

someone told me that reddit is the place to vent and post things that you can't tell anyone in real life so here it is. I'm going to kill myself. my mom has been physically and emotionally abusive all my life and have taken advantage of my naivety and my need of her validation and approval.

What happened last night is my last straw. It's my last year. of college and we had an argument that she wants me to stop with college and wants to kick me out because her boyfriend and his 6 year old child will be moving in the house. My late dad was a bad person, he groomed and took advantage of her when she was a teenager and he was already in his mid 30s. Because of it, when she got pregnant with me, she deemed me as a mistake and was forced to take care of me because that was expected of her by the people she was surrounded by. Ever since I could remember, she'd always take her anger on me and hit me even over such little things even if i wasnt the cause of her anger. She was only like this to me and i dont know why.

Last night was my last straw. I saw how badly she wanted to start over with her life with her basically new family without me. How badly she wanted to get rid of me just so she could pretend i never existed because i was conceived through a disgusting crime that caused her so much pain. I don't want to keep her from her happiness anymore. I don't have the reason to stay alive because other than her, I have no one else and no where to go. This is the least I could do for my mom.
