Grief is so versatile, moving from anger to sadness to joy, and to anxiety to depression. No one can handle their grief alone-no matter if we journal or use the help of a therapist, we need the Holy Spirit of God to help us on a deep level to work out grief, especially compound grief (multiple or back to back losses). God is good and faithful and He will not allow us to grieve more than we can bear.
I would also encourage you, Reader to take grief as it comes, don't hide it but let it come out timing your expression of it for an hour or two and then put it down for next time so as not to become overwhelmed. Grief is to be experienced and not survived and endured.
Learn the lesson that grief is not bad, but a part that makes us acquainted with our own humanity-remember Jesus wept.
