Do not start praying another prayer besides Lord hear our prayer. All this will lead to is a breaking of the rubrics in other parts of the Mass. The Mass is not our private Liturgy, so don’t take that advice. What you need to do is to read your bible and see why the Church has us pray these types of prayers. God can and does intervene in our daily lives. We as humans wouldn’t see any reason to pray that a dead man come back to life, but we know that with God nothing is impossible, remember a guy named Lazarus John 11;43.
Or how about when the destruction of Sodom and Gomorrha was decided upon. Everyone in those cities should have died. But God changed his mind because of the intercessions of one man Genesis 18 20-33. Your intercessory prayers can and do make a big difference, please don’t quit praying them. Let me tell you a story about Madison. When Maddy was born I recieved a phone call from my nephew, he said that my niece was fine but the baby was hooked up to life support, the doctors said there was nothing they could do, they were going to unplug the life support, I got into my truck and drove out to the Poor Clare monastery about 10 minutes away. Now the Poor Clares are a cloistered group of Fransican Nuns. Sister Benadette said they would pray for the child, when I returned home 20 minutes later, the phone was ringing, my nephew said the doctors could not understand it, they unpluged Madison fron life support and she is doing fine the doctors said she should have died. Today she is a heathy 9 year old child so full of energy and life, so I know prayer works I have seen it work, so please continue to pray with your Catholic family at Mass and have faith in God because he can and does intervene. Without God our prayers are nothing but with God our prayers can move mountains. Get a book on miracles and read about answered prayers I think this may help you.
May Almighty God bless us always
