My mom called me a bad mom

I have a 6 month old daughter I'm 19, I'm a single mom as her dad isn't around and left me when I was 6 weeks pregnant so I already knew if be doing this alone and I was on the verge of having a termination but I kept her because I couldn't bring myself to follow through with it and I never could get a ride there at the time.

Well today my mom decided to tell me that I'm a bad mom and it hurt my feelings because I do the best that I can and the tone of her voice that said it made me feel like she said it with her heart and she wasn't trying to be spiteful. It was like she meant what she said and she truly felt that way. I spend time with my daughter but one thing I didn't wanna give up when I got pregnant was hanging out with my friends and I promised myself when I had her that I wasn't going to let having her stop me from living my life and being an average 19 year old. I ask my mom or grandma to babysit her while I'm with my friends which is only 3-4x a week and I'm usually there in the day time unless I have errands to run but I only ask them to watch her from 8pm-5am which is the time I'm usually with my friends. Am I a bad mom?
