2nd baby way too soon!

Alright mamas. I find myself looking at 2 positive pregnancy tests when my little one is (just turned) 9 mo old. I have no idea when this happened, I am breastfeeding AND on the mini pill and my cycle never returned. I know that once my shock wears off I will get excited but right now all I can do is cry and that makes me feel terrible! My husband and I had planned on not trying for baby #2 until my daughter was at least 1.5 and now it looks like I'll be having a baby when she is 1.5! Any words of wisdom or otherwise to snap me out of my funk? I feel terrible but all I can think about is how hard it will be and I feel like I'm going to miss so much with my oldest.
