Accepting reality even though it hurts 😭

My supply has continued to decline over the past 2 weeks. My baby is no longer able to be fully sustained on breast milk and I feel like a failure. My poor baby will want to latch on to my breast (I’ve had to use shields since day 1) and will feed for maybe 5 minutes to get the letdown and then there’s nothing else. I’ve been pumping every 3 hours and will only get 1-1.5 oz each side. My baby cries cause she is hungry so I’ve been giving her formula after she feeds from me. It feels like every day I’m giving her more and more formula. I think my supply will give out in the next few days and that just breaks my heart. My LO just turned 3 months old yesterday and I really wanted to make it to the year. 😔 I’ve been taking supplements, vitamins, pumping, massaging, and trying to latch her on as much as possible but I don’t think my body is responding...
