Feeling Like an NPC: How to Break Free from Autopilot Mode

Do you ever feel like you are on Autopilot? That's how I've felt for a few weeks now and I don't know what's happening. I feel like every time I'm talking to some one, I'm not really in the conversation and just saying things so I seem like I'm there. they arent genuine answers, just whatever I feel like is what they want to here. and Im just doing things every day to fill space. like an npc almost. like im doing things and talking but there's a void behind it, something that doesn't feel real or authentic. I dont know how to get out of it. Advice?
