I can't add much to all the thoughtful comments above. I did look around the web for some local support groups and found the ones below. The one which is called Circles of Hope looks most promising since you may find others in the same circumstances. The other two appear to be general grief support groups.

My thought is that a support would be helpful IN ADDITION to seeing a therapist to process this individually. There's grief, and then there's traumatic grief. The traumatic kind often needs some special attention, such as therapy. This doesn't mean you are going crazy (although I'll bet is sure feels that way!), it just means that you REALLY need to talk about this.

Please take care. Emmy
