Being a new adult who spends and has spend most of their life in hospital waiting rooms, surrounded by elderly people. Being told "just wait untill you get older". Trying to find mobility aids, with mostly elderly people being seen in the example pictures. Elderly people being mad, because you, a disabled person, took the disabled seat.
Young disabled people exist. Young disabled people are valid. Young people can experience pain. Young people can need mobility aids and tools to help them make life easier. We exist and we are valid.
I hope some day, it will be seen that anyone at any age can become disabled. People are born every day with a disability. Mental disabilities don't dissappear with age, and physical disabilities don't just appear when you become an elderly person.
