Ebf and pumping

M
Ugh so im ebf and I'm also a pumping mama, I bf at night and pump during the day in order to get stuff done and work. I'm on a strict 3 hr schedule in order to Mimick a newbor schedule but no one else understands how serious and committing this is. My sister doesn't get it AT ALL and she makes me feel guilty for having to do it. She doesn't have any kids and never has so she doesn't know what it feels like to go past the pumping time and your boobs hurt and be sore. Infact, if she hears one more thing about pumping she is gonna go crazy!! Fuck her. I'm seriously so pissed. Anyone else experience this? I'm gonna go crazy!
