Trust is the key
As I am reading your post, it is conflicting. On one hand you say you trust God then the rest seems that you don't because you are in despair and grief.
You don't say what and why so it isn't easy to pray for you as one must always be specific when one prays to God as not all prayers are heard by Him unless they are worthy.
But let me tell you this. Why be in grief and in despair if you know God will help you? Do you think that He will answer your prayers if you are in this state? Think about it, do you think you merit that your prayers be answered if you continue to be in grief and in despair?
Of course I don't know why you are in this state, but, when you trust completely God, then you must on the contrary cease to be in grief and in despair and act as if your prayers are already answered and of course it will be in His time and not in ours as He also tests us to see if we are sincere.
At the moment, how is your status with God? Are you studying the Bible everyday? Are you praying to God every day thanking Him for all that you do have and for giving you life?
Do you go to church regularily? Follow the 10 Commandements, His statues and laws faithfully? Are you doing all you can so that when you do pray for a favor, that you are found righteous before God to have your prayer even considered?
I bet you never thougth of that have you? The majority of people don't. They forget that one must be found righteous to have ones prayers answered. Not found perfect because in this world which is ruled by Satan, we trip alot, but that our heart is found clean and filled with love for God and doing our utmost to *please* Him so that when we ask for a favor, we can count on Him to give it to us.
Exactly like our parents, didn't we do things to please our parents if we wanted something. Didn't our parents tell us if we were good we would get what we asked for? etc. etc.
Well the same thing goes for our Heavenly Father. We must be good to get.
So forget your despair and grief, get on your knees and ask God to forgive your sins, as we sin every day, ask Him to guide you to be able to serve Him as He sees fit, read your Bible every day, pray all the time, while your driving if you drive, or sitting on a bus, sitting anywhere, and open your spirit to the messages He will send you. You must be able to recognize the messages as it will not be as you think it will be and often a person will help you that you never would have imagined would.
To get, you got to give, to God.
So maybe this is a message from God to you, to say, give my child and you will receive.
If you trust someone, how do you act? Do the same for God.
Trust me, He will answer in His time, if you are worthy. In the meantime, what are you doing to get yourself out of despair and grief.
I will pray that God looks into your heart, that He guides you, that He gives you the answers you need.
But I cannot pray for Him to get you out of despair and grief because I don't know what I would be praying for and I couldn't be specific.
Trust Him completely. I know it's hard not to be in despair or grief..but if you put all in His hands, you will get out of it but you must show Him you do trust Him first and be worthy.
God always helps those who help themselves.
Look at what caused your situation? How did you get into it? Now how can you get out of it?
Like I said, not easy to help someone when you don't know what it is in the first place but God knows and thus only He can judge if you need help or not.
