Maybe I compare other peoples problems in my head as small against mine. I sometimes think maybe I have PTSD as I can't get the trauma around DH death out of my head. Although I coped well with kids/work full time, I'm still tormented in my head. I have had lots of counseling but it still all I think about when I'm not busy with the kids.
The friend I spoke to about definitely experienced this. She was dismissive to the point of being truly offensive when other people tried to talk about their own pain.
It would be the equivalent of:
"My DH has had an affair with my best friend. I'm humiliated, broken and have no idea what to do next. My whole life has been torn from me and I'm terrified about what happens now."
"At least your husband is still alive..." and then discussing the traumatic events around that time and the impact it's had since without considering the pain the friend is going through. It shuts down the conversation and doesn't 'honour' them.
I'm not suggesting that's what you do but, when we are going through a terrible trauma, it can be hard to recognise trauma in others - or respond with empathy. In those instances, it is very easy to wonder what on earth someone is worrying about if their problems seem minor compared to your own.
I know that when my marriage broke down and both my parents died in the space of 6 months a few years ago, I lent quite heavily on a couple of friends for about a year. I look back now and realise that my expectations, borne of my needs, at that time must have been quite an ask for them. They were fantastic for that year but I doubt they would have been there in the same way 3 years on, especially if I hadn't been able to recognise their problems too.
I would suggest that 3 years is a long time to be holding onto the pain and trauma to this degree. It might be worth addressing that privately and sending a message to your friends to say, "hey, it's been a while. How are you?"
