5 week postpartum, how to wean?

I am fighting a losing battle with my mental health with regards to breastfeeding.

I am considering transitioning to formula feeding. Currently, I know baby will take a bottle because my husband has been doing a night bottle while I pump.

What would be a good way to wean to formula? If possible, I would like to avoid transitioning to pumping and then weaning.

Should I feed with small amounts of formula before breastfeeding?

Or should I replace one session per day with formula?

If anyone has any experience to share, it would be greatly appreciated!

Edited to add: supply is not the issue for me. My baby just does not latch properly, so I have a lot of pain. I also have a very fast letdown, leading to baby choking, vomiting/spitting up everywhere, and also constant milk dribbling out of his mouth during feeding. The whole experience is very messy and heartbreaking seeing how distraught he gets.
