No one can put your burden down for you.
You must come boldly before the Throne of Grace. (Hebrews 4:16) You must state your case, your right to come by The Blood and your intent in stepping out in faith because of The Word.
The matter may be as detailed as you like, but in the end, you must tell Him that you give it to Him by faith. He'll take it as He promised.
So many bend under burdens that cannot be borne. His yoke is easy and His burden is light. He said so. (Matthew 11:30)
Letting the matter go in prayer is something that is learned by experience. It does not always feel like something has happened, but that is why we walk by faith instead of feeling. There will be more light on the situation. The Spirit will initiate His thoughts to your mind. Your heart will be calm instead of stirred up.
It is not possible that He will ignore the request.
Tell Him you will obey in this area and He will lead. Talk to Him aloud.
You must be free to move, serve and love.
