Got to agree with both previous comments.
I was struggling with prayer back several months, and it was amazing, but I was RELEASED to pray again when I was reminded that it is a COMMAND from God for all believers to pray.
Also, it's the best way to communicate with God from my end (while other things are important in communication, TELLING is vastly important!), and therefore, needed.
Plus, well, it's peace-giving. Often, when I get frustrated or overwrought, I call my best friend, and we pray together. By the time we're done praying, my heart has calmed, I realize that the world will NOT end, and I am free once again to get about the tasks that lay before me.
But the results vary, depending on what kinds of prayer we're talking about...
There's nothing like being able to be totally honest with Someone whom you KNOW won't judge you for wrong thoughts--nor will He get angry with you for being angry with Him! In one of the BEST times of my life, I spent hours EVERYDAY YELLING at God...telling Him how angry I was for allowing a lot of bad things to happen in my life lately, how ANGRY I was that He had allowed things to happen and that I couldn't make sense of them and it "wasn't fair" of Him...But it was the BEST time of my life (I really, honestly would say it LITERALLY was the best three weeks of my life!!!) because despite the anger, yelling, massive doubt, and hatred, even, towards God, I found myself totally and utterly DESPERATE FOR HIM EVERY WAKING MOMENT OF THE DAY!!! Whenever I was NOT yelling at Him, and didn't have immediate thoughts on other things, I was crying out to Him, BEGGING Him to draw me closer to Him, show me more of Himself, fill me to exploding with His love...
It's amazing to be able to TALK TO THE CREATOR OF THE UNIVERSE about all the things that hurt you, all the things that make you joyful, all the things that confuse you, all the things that scare you, all the things that make you angry, all the things that make you glad...prayers of thankfulness (despite pain and confusion) make you more joyful (or so I've found), and prayers of heartache release some of that pain... We are told in the Bible: "This High Priest of ours understands our weaknesses, for he faced all of the same temptations we do, yet he did not sin" (Hebrews 4:15, NLT)...what can beat having the One to whom you pray being able to understand and feel your pain???
(Sorry...I'm blabbering on so...*sigh* I do that a lot.)
