Is it healthy to be completely independent and talk to absolutely no one at all?

I am a freshman in college and for the majority of my life it's just been me and myself.. occasional boyfriend here and there but I could never find a way to connect with people. My mom seems to think I'm autistic but I do have some beautiful art I've created. My brother is and was my best friend but we are growing apart now with his new girfriend.. he's also never had a problem with romantic partners but could never really make friends and keep them.
