You misunderstand the purpose of prayer.
It’s to build a relationship with God and to do His will, because His will is good for us.
Just because we don’t always “get” want we want does not mean that prayer isn’t working or God is ignoring you
It’s that it’s not right for you at this time.
Don’t stop praying but pray for a higher purpose. That you be at peace, that you remain in God’s grace, and with a spirit of thanksgiving.
Remember, the evil one would love for you to stop praying.
