Dog has different behaviors when I’m around

My dog is almost 2 years old and he’s been like this since he was 3 months. He doesn’t play with his toys, eat his kibble, move around the house or pretty much do anything when I’m around him. I have a camera installed in my home and whenever I’m not home I watch him on camera he’s very active.. what gives? Honestly I don’t understand why he tends to just lay down all day when I’m home. Makes me feel like he can’t be himself around me. Thinking about rehoming him since it’s that bad and he can’t just be himself when I’m around. He’s actually has not eaten since Saturday because I’ve been home everyday in the same room as him. Which is crazy
