Feel like such a failure

I feel like such a failure and I hate myself. I still live at home with my parents, I don't work but I have tried to work before, but it affects my mental health and last time resulted in me being detained under section 2 of the mental health act. My brothers all work, both have moved out now and live with their girlfriends and I'm still at home. I'm 28 now and I feel like since I left school my life hasn't progressed whatsoever, I spend all day with my mum, my dad is out working and I feel so guilty and ashamed that I don't work either.

My days consist of helping in the garden, playing with toys and watching Disney movies and listening to music. I worry what will happen when anything happens to my parents, I've heard them in the past talking about me ending up in a home. That idea frightens me so much. I want to live independently in my own home, and to be with someone, and working.

As I said. I'm a failure. I hate myself and everything I am.
