A lot of people in my family have depression/anxiety and they know and empathize with me since they struggle with the same stuff. Your friend sounds a lot like my sister. I once tried to get JM to share whatever was stressing her out. And she's like "what good does it do to talk about it? Doesnt change anything"
I think for most people in general, we like to talk about our problems! It helps just talking, you know, whether or not the other person can help.
Guess we all deal in our own way..
