So even though you have some vision left, your visual field is small enough that you would be considered legally blind in the US. That doesn’t mean much except that you qualify for certain services that someone with more remaining vision may not qualify for. I’m sure you may not benefit from all types of training, but I bet you would be a lot more comfortable with your cane if you got some orientation and mobility training in order to learn how to use it. Get in contact with the Office of Vocational Rehabilitation, Lighthouse for the Blind, or other Blind association in your area and tell them your situation. Ask for orientation and mobility training. Proper use of a cane will help a lot both with running into people and things. If you wanted a guide dog, you may qualify for one, but you have to learn how to use a cane well first.

An arts academy will open in Augus. It'll have trained teachers who will prepare blind people on how to act in theator. It'll be an on-line program. I'll come back with more information once it its released.

First off, I am truly sorry you lost so much of your vision. I'm sure that is one heck of an adjustment you've had to make on top of the usual starting college stress. I agree that getting help from your local vocational rehabilitation place is a good idea, even if they aren't the fastest or best equipped place in the world. Have you talked to your college's disability services or academic success office? They might be able to help you work something out to make your schooling a bit easier for you. Sometimes you have to push to get them to do anything so make sure to advocate for whatever you feel will help you the most.
As for people being rude, that's how some people are. I was born blind and I still have people spreading rumors that I'm faking it and I'm in my second year of college. I really think that there is a stigma about being blind where people think you are faking because you are able to function as a human being still. You will probably get a lot of "Well you don't look blind" and "If your blind, than how can you do xxx so well?" It takes a while to get used to and I'm not saying it shouldn't make you angry or annoyed, I still get annoyed when I hear things like that, but it helps to take into account that many non-disabled people have no clue what being blind or visually impaired is like. From what I've experienced, people just haven't been taught that blindness is a spectrum and everybody's ability to navigate or do whatever is different. Explaining gets tedious, I know. I try to take the time to explain to people what I can and cannot see and do. It usually works but you will always have those people that just don't or in some cases won't try to get it.

I'm sorry this is so long. It's something I can go on for hours about. I hope you are able to get better with your cane and reach your goals.
