I’m scared

I’m scared I’m never going to be a good mother for my son. I have a 2 year old who I had fairly young I was 18 when I found out I was pregnant and now I’m 21. I’m a full time student and I get up at 5:30am and don’t return home until 5:30pm. My son is watched by my grandma and my mom when she gets home at 4:30pm until I get home. I am a prenursing student and I recently got into my colleges honors program. I try so hard to balance school and having a toddler. I’m scared I’ll never give him a good life. I’m scared I’m going to fail him. My mom and grandma won’t let me live it down that I shouldn’t be going to school. I come from a family with lots of stay at home moms and I’m also the first in my family to go to college so they don’t understand the work load. I’m scared that me going to school is actually hurting my son. My mom even told me I’m traumatizing him because I’m not home. I guess I’m just looking for some comfort.
