Failure I am

I dont know what to do with myself. My mother told me i failed every class of my sophmore year, that im a failure, stupid, a waist of time, that im on the right way of being homeless. She tells me i cant go to summer school cause she doesnt want to waist her time and that i have to get a job to help myself from now on. I live right down from my school, about one hour walk. I can do it myself. I dont need her to help me. She said i dont get a second chance so i say”But thats the same as taking the grade over again. You say you want to help me but then your holding me back?” What a stupid thing of me to say. I wasnt trying to say it was your fault mother, im sorry. I know im never getting anywhere. I know that theres something wrong with me. I have a therapist but mother tells me not to tell her anything that would get me taken away so i have to lie. I dont feel better, nothing helps.
