Breastfeeding vs formula questions

I’m a FTM, 33w. SAHM.

What are your thoughts on breastfeeding vs formula?

I had planned on doing breastfeeding this whole pregnancy until I recently had my baby shower.

One of my cousins that breastfed said it was super hard and increased her PPD/PPA levels to where she had to stop after a few months for her mental health.

Another cousin said she tried really hard to do it but after 2 months and baby wasn’t gaining weight well, the doctor had her switch to formula.

My mom and sister were never able to breastfeed.

I’ve had pretty bad prenatal depression/anxiety, I had to seek help from doctor and sources. I’ve discussed getting on anxiety meds after baby is born (been on them before) but not sure exactly cause I didn’t do well on meds before.

My husband is gone during the week and sometimes weekends for weeks at a time for work. I’m worried about being up every 1.5-2 hours with baby while having to take care of the house/pets/everyday responsibilities all in my own.

I’ve taken a breastfeeding class and it was VERY overwhelming for me. Lots of things to do, holding positions and rules etc.

I know breastfeeding is generally better for the baby but can formula be just as healthy for baby too?

If you choose to just formula feed do you have to buy a breast pump? Does your milk just not come in? How does that work?
