I had two friends die this year. One suddenly collapsed. He had been a good friend but we had drifted apart when he moved to a different town. I could have gone to the funeral but I didn't feel it was right. The other was a friend from student days. I had been back in touch last year via social media but I hadn't seen him in about 20 years. I suddenly thought of him one day and noticed that his twitter feed was very quiet. I googled him to find that he had taken his own life at the beginning of the year.
I don't know how to feel about this. I feel that I have no right to grieve as I hadn't seen either of them for years.
I don't expect any answers or responses, I just wanted to air my feelings.
I agree with above poster. But also the other way round too - if you are not feeling anything strongly it may be because you aren't actually feeling very affected. After all, they were not a part of your life now. Which is fine too.
