I am seeing that you have been through a situation where you needed one of those "miracles" and you prayed for an answer from God, and He didn't answer. I would like to encourage you that God answers every prayer you make to Him, if made in faith, in believing that He answers His children's prayers. The problem is, that sometimes the answer is, No.

Like a loving parent who has a child that just want's to eat cookies all day, and not eat proper food. The answer is No. Why? Because it is not healthy, and yes would not be the proper answer. Why? To be mean? No. Because the parent sees the whole picture.
Sometimes we get in the place of telling God how to answer our prayers, and when He does not answer them the way we want, we take that as Him not answering. But, we have to remember, He sees the whole picture. Even Jesus, when wanting to have the suffering removed from what he was about to do on the cross, prayed, Saying, Father, if thou be willing, remove this cup from me: nevertheless not my will, but thine, be done.
Luke 22:42
When we pray, we must pray according to His will, then we will begin to understand that sometimes the answer is, No. 1 John 5:14 says it all.
God Bless
