Once someone has been born again, they have every thing they will ever need right on the inside of them. That place? Their spirit. Why? You receive Christ and your spirit becomes identical to His. Galatians 5:22-23 - "But the fruit of the Spirit is love, joy, peace, longsuffering, kindness, goodness, faithfulness, gentleness, [and] self control." You've already got it! But how does one bring something from the spiritual realm into the physical realm? As for the fruit of the Spirit, you need to go to believing that you already have it! I'm sure you've probably asked for some sort of peace, but once someone already has something, it's easier for them to believe they have it, right?
John 14:1 - "Let not your heart be troubled, for you believe in God, believe also in Me." Jesus was telling His disciples to do this before He was going to be crucified. I mean, that must seem pretty far-fetched - Jesus was about to die, and He told His disciples to do that. He would be unjust to give them a command that they couldn't do. In fact, He was telling them that they should rejoice because He was going to His father! Also, Jesus told His disciples to do this when they weren't born again. That means if they could do it then, it's very possible for us to control our emotions now. I'm not saying it's easy, but it's very possible.
John 3:16 - "For God so loved the world that He gave His only begotten Son, that whoever believes in Him shall not perish but have everlasting life." Widely known verse, probably most memorized/quoted. I bring this verse up because it's the one of the best statements God uses to describe exactly how much He loves us. He loves you, BrittanyBoo, personally. He loves you more than you could begin to understand, although the Bible paints a darn good picture. He carries your picture around in His wallet. He loves you! This next statement will seem weird, but bare with me - if you even begin to feel depressed, you've got to look in a mirror and minister to yourself. I mean that you need to keep telling yourself that God loves you. Faith comes by hearing, and hearing by the Word. Eventually (however long it takes you, there's no set time) you'll get to a place where you may feel His love tangibly. Then again, I'm not quite sure what brings this, but it's happened to me a couple of times.
Lastly, as far as unanswered prayers go, it depends on what you're praying sometimes. There are some spiritual laws that need to be followed (I'm not sure what you've been praying for specifically, so I'll leave it at that). Rather than thinking that your prayer has gone unanswered, believe that He has already answered it. Your senses aren't always reliable, and seeing isn't always believing. God only wants the best for you. I have more on this area, but my brain isn't working at the moment.
John 14-16 should help you a lot. God bless!
