I was just outside smoking a cigarette & a random guy passing stopped to talk to me. It was really awkward. I listened to what he said but when it came to say anything back my mind was blank so I just mumbled simplistic responses.

I used to be a reasonably good conversationalist but now I really struggle to know what to say to people. It's literally like my mind just draws a blank. I wish my brain would just start functioning properly again.
