@trying2learn,
You seem "stuck" in your grief. You MUST start talking about her and how you feel - or all these feelings will affect your own physical health.
Other people at grief groups are going thru the same thing. You don't have to tell EVERYTHING, just share and listen what you can. You are not the only person who hurts like this.
Do this for your own health.
Good luck. It does get better, it just takes time.
