Being told 'No'

When God tells you no.... it can be a hard thing to accept sometimes. He tells us His plan is better than our own. Then how come it can hurt so much when He does say no? I want a baby so bad but its just to bad so sad. Im so so so ready. Financially and mentally ready. I did everything right. Nothing holding me or hubby back! The answer is still no! I'm angry and I'm hurt but I'm not suppose to be but guess what, I am!
