How do you hope?

We haven't found my parents dog yet. We have had some spottings, some leads, none have panned out. There is such a bizarre spiritual component and it makes dealing with this even harder. My kids keep praying and hoping and they have such confidence that Tawny will come back and that we will find her. I, on the other hand, have this human condition where I look at the other times lately that I have experienced loss and grief and see this going that same path...no happy ending. Maybe I am feeling beat up. I understand the meaning of suffering and why God allows it. It is the relentless suffering and the loss of happiness and hope that I'm not handling. I should be able to but I am failing miserably. It could be stress, lack of sleep of any of the other myriad of components that have me feeling overwhelmed. I want so bad to trust and to put things in God's hands. I did that with the baby and the baby is with God now. Not once but twice. I'm sure it would be best not to judge a moment or event on past history, I'm just not very good at it. Thank you all for the prayers. My hope is to see the good that comes from this if there is no happy ending.
