Disappointing Daughter

I feel such a disappointment. I feel like my mum hates me. I can't do anything right. I needed to be alone tonight. So I slipped into the shower room, pulled my dressing gown hood up and had a cry. I feel as though I everything I do just isn't good enough. After I was all cried out, I curled up on the floor and tried to sleep. My mum came in after about one hour. She had not realised I was upstairs. She thought I had been drinking or taking drugs or being sick. I never told her I had cried. My eyes were all swollen and red raw. She didn't notice. I can't believe that.
