Dearest friend
Oh it is right, perseverance in prayer is everything, because you are now doubting God is even listening to you, now when you doubt on God , how can He help you? You dear friend, have to believe that mountain you need moving God will move and He will do it in the way He wills it which is not down to human wisdom, but what God thinks is best, so trust God in His Infinite and Eternal wisdom in which He knows is best.
You have begun to lose hope in the Lord our God, now please don’t do that. Even when trials fall upon you and it looks as though all is lost, this is the very time to run to Him and cry to Him ‘God, God help me!’ in all humbleness and knowledge that you cannot resolve this yourself because without God our very life would cease, He is the Divine Creator and Sustainer of our universe and life.
Go before the Lord Jesus Christ in the Blessed Sacrament, go down on your knees and talk to Him as your brother and best friend He is, ask Him to ask the Father for you, ask Mary to ask Jesus for you (all things go through Jesus to the Father, and from Mary to Jesus, that’s the way of it )
If you lose hope in God , then He cannot help you, this is a lesson in hope and trust in Him, that however you measure time, the Lord does not and His time is the best time and you have to trust Him in this, there is rythmn and reason and method in everything God does and you must trust Him
God Bless you and much love and peace to you
