Am I a bad mom?

So I EBF my first for 15 months (he’s 17 months now) I’m 35 weeks pregnant and I don’t think I want to breastfeed again. I have depression and would really like to get help and put on meds for it, I’m tired all the time caring for a toddler. I can’t see myself being happy waking up every hour to feed and every three hours to pump. Does this make me a bad mom?.. I’ve been stressing over what decision to make for about a month now and I don’t want to be a bad mom, I want what’s best for my kids, and I know breastmilk is better but I don’t think I can do it this time around.
