I reread Emls a few times before I hit send when I'm struggling.
I don't type so thankfully my messages are short.
When I'm very sick I have complete memory loss. So I don't bother with apologies.
I've only lost one friend over the years. He was a former boyfriend anyway,& I think he got married. Dropping me was probably a condition.
Or maybe he got sick of my episodes.
I've lost other friends, but those I ditched myself.
Bottom line. People are going to be able to be your friend or not.
