anyone else get extremely emotional when stopping breastfeeding?

I just had a baby 5 days ago and nursed my son (he’s 2 next month) up until the day I left for the hospital. when I came back home he wanted nothing to do with me and I felt sad that I never had a last time with him and I didn’t realize until I brought my baby home but that was how we bonded and how I got him to sleep. Tonight he wanted to nurse and Idk if I’m crying because he looks so big compared to my daughter or because I don’t know if it’s going to be the last time but I’m a wreck. I literally can’t stop crying while I’m holding him 😭
