#1. You are so thoughtful to be thinking of her. Don't feel guilty.
I am sorry for your loss.
In 10/2015, I lost my husband suddenly. Grief is hard and different for everyone. We were together 30 years, almost 27 married and 1 daughter, 20 when he died.
I tend to tell people "I'm fine" and move on because I know people don't want to discuss it really, especially after some time. Theyre trying to be nice and I appreciate that. I'm private and don't talk to a lot of people about it. I try not to call/text a lot of people and I look for other ways to let it out like exercise.
People move on to their lives (families and obligation), their lives continue and we (spouse/caregiver) have a new normal to adjust to.
I went to a grief support group over a year which helped because I was in a group where everyone had lost their spouse/SO, etc. it helped me to see people in the group who were further down the grief road than I was. Now that I'm in that part of the group with my loss being 21 months ago, I'm not going to grief group as much because every time is like ripping the bandaid off again and I leave raw. It still feels very raw and new and it's just 21 months out.
Only those who have been through it know how it feels to lose the partner you were going to be with the rest of your life.
I read a lot of books. I keep a journal to this day that I write in daily, no excuse. I've found that I go back sometimes and see how I handled something in a previous journal entry and check on my progress.
Here are books I enjoyed that were not too heavy but a good read.
1. I Wasnt Ready To Say Goodbye by: Brooke Noel and Pamela D Blair PhD
2. Confessions of a Mediocre Widow by: Catherine Tidd
3.Heartbroken healing from the loss of a spouse by: Gary Roe
These books have real life experiences, some sudden death like mine and from a long term illness like your brother. Both types of death are difficult to go through.
My thoughts are with Annie and I hope she finds comfort in these upcoming long days.
