Fed up of life !!!!!!!

My mum is blind and has depression anxiety and Ocd. We have an alright relationship but the other day she said something that just broke me. She said I'm a waste of space. I don't feel like she loves me at all she never said I live u never hugs me or kiss. I just don't know what to feel. Ps im 12 years old and ijust want to say if anyone comments iwon't reply but i am thankful for any reply. What would u feel like if ur mum said that to you
