You need a community social worker and a doctors note to get on some type of disability. 2 doctors notes to be exact. One from a phycologist and another from a family doctor. My place of work use to handle these all the time, it's normal. There are two different types of social workers. You need both. You also need to gather your medical files so you can apply to disability. But you have to request them first.
Plus you need to find a drop in center where they feed the homeless and find a local food bank so you can budget your money.
