People with social anxieties will probably never have it easy. Not especially if they are studying at a college. Because there is no worse place for them than a place very huge amounts of students are concentrated at every step they make.
Well, that of course does not mean they should not attend college. Letting anxiety control your life is not a good thing. And that is what you should know. Slowly, you will make it through. All you have to do is try to connect with people. And to enjoy being on your own sometimes. Actually, eating on your own is great. And you should definitely try it.
