Struggling with feeling overwhelmed in conversations

I’ve noticed that I feel completely overwhelmed during conversations when they go beyond simple small talk. If someone asks me for my opinion on a topic, especially if it’s philosophical, intellectual, or requires some deeper thinking, I mentally shut down. My mind feels foggy, I can’t think logically, and I struggle to articulate my thoughts.

It’s not that I’m socially anxious, I’m fine with casual chats and short exchanges. But when the conversation requires me to explain something complex or form an opinion, I feel completely stuck. I either ramble and don’t make sense or can’t respond at all.

I’m starting to feel frustrated because I want to be able to hold deeper conversations and share my thoughts without feeling overwhelmed. Has anyone else experienced this? How do you stay calm and think clearly in these situations? I’d really appreciate any advice or strategies that have worked for you
