Achieving integration & inclusion by putting severely disabled kids in normal schools is a fairy tale. Integrating into the world at large is a separate issue - you're not stuck with the same class throughout, you're not dependent on the same teachers. Arguably, you face some of those issues when you get a job but there's a much larger choice and the people around you are at least adults, in a hopefully professional environment. I just don't see the case for having to go through school as a definitive outsider and endure guaranteed bullying to somehow prepare you for the world better. Trauma doesn't prepare, it disables further. No idea where OP lives, alternatives will obviously depend on that and/or OP's ability move accordingly.
