Disabled but not Disheartened

I am a mentally disabled girl who cannot work a normal office job. It has always been my dream to be successful. The only way for me to take care of my family is by starting my own business but I don't have the capital. I got fired from my last job for asking for a short break after my grandmother passed away. I have had morning where I lay naked, vommiting and shaking on the floor and still got up to go to work. I want to show the world that I am capable but I need you help.
