I need help!

I wanted a baby so bad. I took fertility medicine to have on because I have PCOS. Now she’s here and I’m struggling. I’m a full time college student, have a job, and I’m trying to be a mom. My mom watches her while I work. She has her a lot and I’m constantly getting comments like “wow you must be missing a lot” and “doesn’t your mom have her all the time”. It’s mentally getting to me. I’ve had such a hard time putting her to sleep lately because she cries on me so much (she’s 7 months) and I just feel as though she hates me. I’m not a good mom. Maybe that’s the reason I couldn’t get pregnant on my own it was a sign. I want my life to just end for her sake. Life is just getting to me so bad. I’m typing this from her bedroom floor as I’m bawling my eyes out wishing I had answers. Why am I not a good mom? Why can’t my daughter like me? Why do I hate my life so much when I have such a beautiful miracle? I’ve never felt so low in my life. Mamas has anyone else gone through this? What can I do? I’m screaming out for help right now because idk what else to do!!!!
