How long will it hurt this bad :(

I am a FTM on day 3 of pumping every 2-3 hrs.

Can someone give me hope- that it won’t hurt this bad forever :( How long did it take to get used to this ?!

I want to cry every time I pump, it’s so painful for me. I can’t relax and I am sure it is impeding let down.

I also have a awful blister on my left nipple.

Any tips from more experienced mamas? I’m losing my mind.
