Facing Intense hunger even while eating.

This has started only during lockdown. My hunger does not seem to satisfied no matter how much I'm eating. Even while eating food my stomach makes sounds. When eating, It feels like the food is not reaching my stomach at all and I'm constantly feeling hungry. Because of this, I developed acidity and burning sensation also and after some medicine the acidity has subsided. I feel hungry but don't feel like eating or feel nauseous or bloated while eating. My hunger is not getting satiated. I'm feeling weak and sleepy most days and even feel cold nowadays. Sometimes my throat n neck feel very hot and uncomfortable. (I'm also facing severe hair loss because of this) Some days it's so bad that I cannot sleep. Please advise.
