Would this be pointless?

I had a mother figure all through high school. We were close, i told her everything, she was my rock when i was hurt. Then in my senior year I got depressed and she disowned me. In a cry for help i told her i was suicidal and she cut all ties with me and said she didnt want the pressure. It tooks months of crying and begging God and therapy for me to even think about her without falling apart. Now i'm better and going off to college. We hadn't spoken for months but i made her a scrapbook of the good times to remember me by. after that she got emotional and asked me to have lunch. I hoped she would bring up what happened 6 months ago but she didnt. neither of us did. But she didnt even ask how i was doing now. I dont see how we can be friends. I feel like i need to be heard for once. would it be wrong of me to meet her again and let her know how i felt. I dont want anything from her, just closure. She said some really cold hurtful things when i was at my lowest. I need to hear her perspective and tell her mine. Pointless? sorry, this was longer than i intended.
