First, make sure your mother's concern is not about the student loan debt your will incur in the further college. Ask your mom if you paid your own way to the further school if she would be OK with it. If she says no, then try to find a middle ground, like living in an accommodation that is not your mom's house, but staying in your home town for the first two years. It's hard to tell if your mom's objections are rooted in control, wanting to stay close to you, or concern about your maturity living in a distant town. If you can boil that down to a basic concern, maybe you can find a middle ground that pleases both of you.
