I don’t know

Sometimes I get flustered and want to disappear. I have a husband but sometimes I feel like I’m raising a baby on my own. I have a 7 month old breastfed baby , sometimes she cries just for me. I understand that but I feel like I don’t have me time. If I ask for him to get the baby while I use the bathroom he’s clocking me. Sometimes I get sad and just watch her cry. Not too long probably like 3 mins max. I feel bad afterwards. I don’t know what this and don’t understand how to fix it.
