Depressed about breastfeeding

My daughter won’t latch anymore. My husband wanted to give me a break once in a while so we introduced a bottle last week (4weeks) She was doing just fine breastfeeding and with one or two bottles a day. Now she maybe will latch for 5 minutes and only if I’m really full then she refuses. She will fuss and fuss because she’s hungry but won’t breastfeed. She was awake from 10pm to 6am trying to eat... my husband finally gave in and gave her a bottle at 2 before he went to work,but she was still hungry when he left. She wouldn’t take the bottle from me so she just fussed until she finally feel asleep. She slept for 2.5 hours now she’s up again and hungry. She won’t nurse even if I use a nipple shield. I’m so upset that I can’t feed her. I miss our connection. I don’t know how to fix this, I’m going to see a lactation consultant next Thursday at my 6 week pp check up, but that’s still a week away and I can’t get to town any sooner. I’m so exhausted and depressed. I just want to breastfeed my baby and I know the more bottles my husband has to give her the worse the situation is going to get. I don’t know what to do to get this back like they were.
