So yeah i have SAD and am in therapy.

My therapist wants me to try and casually talk to people.

My problem is whenever im around people my mind goes totally blank and i dont know what to talk about whatsoever.

But i have a very good friend, whom i can “easily” keep a conversation going with, and he is the only one, i can barely even talk to my parents.

Also i sometimes have imaginary conversations with people im about to see etc. where i find myself quite funny, but when i see them irl everything shuts off.

So i guess what i need help with is how i can practice talking to people when i dont have any thoughts during conversation?

I have smoked weed at times which makes me quite good at talking to people and im wondering if thats just the way to go and just smoke everyday.
