Why do you want to transfer to somewhere higher ranked? Is that going to make you happier?
First, be an adult and talk to your roommate. If you can’t do that, talk to the RA who’s supposed to help mediate these issues. If your roommate is treating you poorly, make it clear that it’s not acceptable. You live there too, so don’t be a doormat.
You don’t like where you are, so yes, consider a transfer. The problem will be that your grades are not good. Any transfer at this point will be a sideways move. The grass will not necessarily be greener at another school. You have to think about your real reasons for transferring.
I suggest you go to the academic advising center on campus and have a frank conversation about what you need to do to get to a better university. Your first goal should be to raise your GPA. Go to professor office hours and the tutoring center. Yes, you might have to spend longer getting your degree. You are young so you have time. You should also go to the campus counseling center ASAP and book an appointment. Go to the career center and ask about what careers might be good for you. They probably have assessment tools that will help you discover what might be a good fit. Look at all the various internship and job shadowing possibilities on offer. Apply to them.
In short, be proactive. Stop fretting and worrying, and instead take steps to make changes.
