@ mel i have a lot on my plate aswell,but i have learnt something and that is you need to concentrate on one area of your life at a time,pray for one area for 3 weeks a month even 40 days or just 3 days combined with a fast.the lord is mighty but their are areas of our lives that the enemy doesnt want to let go off,this is when we have to go into battle and fight one area of our lives first and concentrate on that area for a period of time then move on to the next,there is also a chance that the lord has answered some of your prayers but your going to have to wait for his timing/wisdom concerning the desires of your heart.i too am waiting for certain prayers but i believe our lord has heard me and is at work answering them
