Pray for Kimberly

I do quite a few Bible studies but I really enjoyed this one more than all of the ones that I have done.  I am having trouble letting go of pain that I’ve been holding on to for a while.  And I know in order to move on I must let it go, but I am not sure how.  My boyfriend died of an overdose and I found him.  I never got to go to his funeral.  I don’t even know where he is buried.  So I have no closure.  How do I deal with this?  Any suggestions?  I’m not a crier.  I haven’t cried in a long time.  Thanks.
