My sister and my boyfriend are my closest friends. After many years I opened up to my sister about my social anxiety and she said: you'll grow out of it. It's nothing. You just have to talk more. It's not true. And she kinda said that I'm faking it. 
Later I opened up to my boyfriend about being kinda depressed. He said: that's not depression. You just like to be sad. You're getting yourself into it on purpose. 
I never told anyone else about this things, and will never ever try again.
