Needing breastfeeding advice

HELP!? I’m 4 days PP today and my milk is coming in for sure. Didn’t pump any night last night- long story, I’m having some personal health issues. And she’s not staying latched still, I feel like it’s cause she’s not getting enough. BUT I woke up, leaked through my shirt and they are so hard and hurt so DANG bad. TIPS!? Also I’m wanting to keep trying so I can nurse her once my supply is enough for her to keep eating. (I am going to have to consult with my dr about a anxiety medication safe for breast feeding.)
