A lot of us have been taught how to ask but not how to receive. So you're praying for a job, child, change of financial fortune etc but don't know how to receive.
All of a sudden people say things like I don't think God cares about or likes me. And the reason they say such things is because they have been trying to secure God's attention to change or do something but it's not happened.
A lot of people spend time fasting and praying hoping something significant will happen to them. They really want to see results and hope for help.
There are people who are overwhelmed and stressed out and depressed. Some are married and want to have their baby, some feel under-resourced and are praying God enlarges their costs.
Other people hear other people's testimonies and one part of them is excited, while the other is asking - "God when will you do it for me?" Others are single and they feel the clock is ticking.
Some people pray and have no faith in the power of prayer. Almost as if "God when you're ready to answer you will answer because I've prayed & fasted all these years and there's nothing you've done."
Sometimes you are so discouraged about prayer that you need a community to encourage you to keep praying.
Mark 11:20 - Sometimes because the answer to prayer is not instantaneous, we think God did not hear us. But, the truth is there is a process in place that is working out your prayer being answered.
Some people ask, why should I pray? God should already know what I want.
Prayer is permitting God to do what we want (e.g. A landlord has to get authorization to enter in his tenant's flat and fix faulty plumbing, so also God has to be given authorization through your prayers, for Him to act in your life).
