need some feedback ladies!

I had my little girl a few weeks ago. I've got emotions that are out of control! This is our second and last baby, it would be very risky to get pregnant again. But I'm only 25 and having a hard time accepting it. I don't think I really want more but then I question it... It makes me sad to think that the two best moments of my life have come and gone and this is it. Part of me wants a third but even then I feel like after having a third id still have these feelings of wanting more. Am I crazy? Is it the hormones talking ? It's so frustrating and I feel like nobody understands
