My best friend thinks I'm making a big mistake in going to see my mother. Does she have a point?

My mom said to me over the phone (finally she answered) that she wants to see me sometime. I'm thinking about going to see her. My best friend things I'm making a big mistake. She said, "If you're thinking about living there then I'm going to end up being very lonely and you're just going to have a great time and you won't even wanna come back. I heard enough already. You're going to forget about me!" I told her we're always best friends but I don't know how long I wanna stay. I love mom and wanna reconcile with her but my best friend flat out told me, "There is one thing I don't understand and I don't wanna sound brutally blunt but...why do you wanna visit or stay with the woman that made it clear that she doesn't even want you? She walked our on you guys to have her own life and let you down so many times and only thinks about herself. Why are you even considering this?" That really strucked me with this and kind of offended me but I knew she had a point. She said I keep denying the my mom doesn't give a shit about us and doesn't want us anymore. Is my best friend right? Is it worth it. I really wanna be with my mother. It hurt is really bad that she abandoned us and doesn't even regret it. I told her there's people she can hang with but she rather hang with me than the others.
