I've had this kind of thing happen to me many times and, in my experience, there is no better way to deal with it than to just leave it with the LORD. After all, since we're doing everything as to the LORD, there's no loss involved, really.
The earth and the cattle on a thousand hills belong to Him. I've had to learn to think of absolutely everything I possess (right down to the bathroom tissue) as on loan from God. I'm just a steward.
I also find I have to pray daily for the grace to keep me mindful that forgiveness is not merely an event, but also an essential attitude, a part of the lifestyle of a Christian. I often hear Christians testify that they are having a hard time forgiving someone and that they've prayed so hard for the ability to do it. Christ had no time to kneel and struggle with His Father for the ability to forgive when the High Priest's guard struck Him in the hall of the Sanhedrin.
If we earnestly pray for a generally forgiving heart (for we truly need it), instead of focusing on those who have wronged us (not that we shouldn't pray
for them), God will surely answer, and we will have an experience as we've never had, a closeness to the LORD we never thought possible.
Of course, all of this is relative: It doesn't happen overnight, usually, and there is no limit to the amount of this spirit we may receive. If we "only believe" (Mark 5:36). And, of course, I know I am preaching to the choir here, but for the benefit of others who might be struggling, I thought it should be voiced. :)
Exodus 32:32 KJV: Yet now, if thou wilt forgive their sin--; and if not, blot me, I pray thee, out of thy book which thou hast written.
Luke 23:34 KJV: Then said Jesus, Father, forgive them; for they know not what they do. And they parted his raiment, and cast lots.
