First of all, I am sorry for your loss and there are no words that can be said to remove your pain.
Dealing with the grief is necessary. I used GriefShare which is a multi-week religious based process and was very helpful. I might have realized more benefit if I was a member of the church. I might have liked a traditional group setting away from a church because the visual church setting became a negative visual reminder. Taking time to journal your grief will always be helpful.
I am sorry for your loss. GriefShare is a wonderful program and is Christ based program. That means we use scripture, and do talk about God. We are in no way there to suggest a specific church or talk religion. Many groups are now meeting online, through a program called Zoom Meet. This way you can watch the video and participate in a discussion after the video, in your own home.. It is usually a 2 hour program, and runs for 13 weeks. You can find a group, or more information at: www.griefshare.org/findagroup.
I would be willing to help you find a group in your area, if you would still like to get more from the program. Text or E mail me. Marcia 775-253-0201 or firstname.lastname@example.org
