Emily as a fellow autisitc sister in arms i can empythize with you on your struggles. I am not in your shoes but i can relate in certian ways. I think everyone here needs a big chill pill. I will not down play your struggles. but there have been alot of people who have given you some really good advice. I doubt anyone here wants to see people with disabilities be discriminated agaisnt, or atleast people with a heart dot want that. But at the same time, people have been trying. I have said try a customer service hotline for a store like Sears or what not. Others have said maybe do some kind of farm work. You will have to learn how to manage a computer in one and in the other you will have to be willing to labour around. You can also do what i did as a teenager living in rural Ontario and do some independent landscapinng or find a landscapping company. Lawn work, building treches, building fences, snow removal, house seceruity, tending to plants, ect is really fun if you can bare the heat and seeing how you live in Tennessee and not Ontario i can safley say the winter temps will rarely be physically impossible to not start/finish a task.
This is not a lecture and please do not take it as one, but many people have been trying to give you ideas. It will be up to you at some point to decide what one is best to take. You may even have to do some job hopping. I will say avoid kitchens and construction. They are very fast pace and at times both can be grueling hard. So try something like landscaping, it is , in my experimnce, slower pace (but be prepared to sweat like a hog) comparred to other things but you learn quite a bit or do a cusotmer service line.
