My brother-in-law suffers from panic attacks, and has no idea why. He is very open about discussing it in front of all his siblings including my partner, and myself. I like him, and get on fine with him, although we don't know each other well.
He is several years younger than me, and recently I sent him a long email about it, totally unsolicited. I wanted to empathise and share my experiences, and I'm just better in writing than in person.
I said that I hoped he didn't find it an intrusion, too personal, or too preachy, but that I get it, I understand, because I have for many years experienced emotions which don't seem to make any sense - not panic attacks for me but mood swings, guilt, shame - and that there is a wealth of techniques and methods out there: counselling, CBT, etc, and to keep trying to get to the bottom of it. The email went into quite a lot of detail about the things that my own efforts have uncovered about my own issues with my family - possibly way too personal - but also said that of course I'm not saying that's what it is for him.
He didn't reply, which is not out of character for him, he is often bad at getting back to people. And I am assured by my partner and his sister, that he won't have been offended, he will have been grateful for any efforts to help, but I am still unsure. Was I patronising?
