Dyslexia is not something that prevents people from working. Go see the people at Goodwill. They can help you get some food. They can also help you find someone who can teach you coping skills for dyslexia.
salvation army, churches etc here in texas u call211 and they will give u a list of places to go for help
Go to a shelter or any other community assistance programs .. Just like anyone else. But dyslexia isn't normally something that prevents someone from getting a job and supporting themselves.
