Ahhh this is tough la, I feel for you! A few of my mum friends went through the same thing, try introducing the bottle way earlier next time, tapi since your baby dah attached to bf, you boleh try pausing for a day or two and let your partner or family member offer the bottle instead (sometimes they reject from mama sebab tau ada direct source haha). Some of us also found that trying different bottle teats or warming the milk helped, and honestly tak semua babies akan accept botol jadi don't stress if it takes time, maybe express milk and cup feed in the meantime while you're figuring it out, atau start work part-time dulu while baby adjusts?
