How do I get in to other roles as a support main?

I main support, and I've been trying to get in to other roles but I'm finding it really difficult. Morgana is the only real mid I can play, and I'm clueless when it comes to all the other roles. I've been trying to practice in norms but all that ever happens is that I get stomped and lose because most other people aren't practicing their off roles. How do I play other stuff besides support?
