No. not at all. I am motivated to do as much as i can for such unfortunate ones. I work with little children who are mentally and physically challenged and just get frustrated that nothing much is done for them. Honestly I wish people could do more then running and hiding away from them in fear.
I think many people feel that way when they have not been around people with severe disabilities. It's unfamiliar and so we don't quite know how to behave and that can embarrass us - so we get nervous. Educating yourself will help. Volunteering and getting to know people will do something even more interesting - you may no longer notice a disability. You will just see the person
No, because I'm a professional nurse and bring a higher level of understanding to my interactions with all kinds of people, and I have worked with people with "severe" mental and physical disabilities.
