also just to add, if these people are just rude people then its not worth your effort trying to change who you are to suit them.
most of these people you will rarely(if that) see again once you have finished college, dont quit the course, just be you, people who are genuinely nice will not be mean to you or ignore you.
If you are autistic you already have difficulties with social scenarios, why bend over backwards for these people, just be you and do what you feel is comfortable for you.
whiffey is right in a lot of ways as well, dont let societies expectations make you have to change who you are to try to fit in, you will only be more miserable trying to maintain a persona that isnt natural. you are not alone, find friends that are on your level, ignore the loudmouths.
