Am I selfish?

Am I selfish for stopping breastfeeding at 8 months? breastfeeding was going fine, but my mental health was in the tank. Now that my babe is almost completely on formula and table food, I feel 100% better than I have since I got pregnant (mentally speaking).

I know that’s great and my mental health is important but WHY do I feel so selfish? Why is this so emotional? If it’s the best decision, why is it so hard for me to grasp? Baby is fine with it, he is more than happy to take a bottle and at this point would rather not nurse unless it’s the middle of the night. If he’s so fine with it, why is it so hard for me?

I would love to hear some positive weaning stories from you folks. I just need reassurance that breastfeeding for 8 months is amazing and its okay for me to let go of it now. I also probably just need a good cry.
