I have nothing to say

Lately I’ve been feeling like I can’t talk to people. I am a full time student with a full time job so I don’t have much time to do anything else. I hangout with friends maybe once a week if that. But I GENUINELY don’t have anything to say, like nothing is going on in my life right now. Same shit, different day. I don’t have any stories to tell or anything. I feel like the most boring person alive. Sometimes I’ll even get so in my head when I’m around people and I can’t find anything to say. Like I’m exhausted and I’m a very private person too but why do I have nothing to talk about? Or do I just not know how to have a conversation?
