My LO doesn’t say Mama

I am concerned that my now 1YO isn’t saying Mama. It was the first word/sounds she ever made back at 3 or 4 months, but now she rarely, if ever, says it and TBH I’m a little sad and worried. I’ve had a tough go from the beginning, dealing with PPD and anxiety, feeding issues and, more recently, sleep struggles,too. So this mama is exhausted mentally and emotionally. I worry I’m messing up though, and that she doesn’t love me. Has anyone else had a baby call her dada (which she literally calls every one and everything) or not call start calling her mama for a long time? I need support and/or to not feel alone.
