Well the nature of this is to not trust people so its hard for me to talk about it with anyone.
I disagree with you about non sufferers having empathy....I'm sure some like you do...but having to work out who I can talk to is a real problem.
Every now and then I do 'make friends' with someone who I feel OK with and tell a bit more than I usually would. The last person I did this with, not that long ago decided to steal confidential papers from my business and set up in competition and quit her position at my place by text.
Then there was my ex in laws that when my first husband broke my bones then ran off with someone else leaving me with a new born baby and a toddler, said they will always be there for me and how ashamed of their son they were. 3 weeks later they were telling lies in court and trying to get custody of my kids.
Yes I do talk to my husband, though not on a constant day to day basis. He knows my problems and where it stems from, but I tend not to tell him every time I feel bad. I think he can guess mostly anyway by my behaviour or anxiety symptoms.
