Calorie troubles

m19, slightly bigger than average build. A Little while ago i stopped eating foods that i thought weren’t adding much to my diet. Cut out the sweets, unhealthy snacks, started choosing water over the occasional chocolate milk etc

Fast forward and i started monitoring my calorie intake because i don’t feel good , only to find out I’m struggling to reach 1500 calories a day . Afaik a guy my size needs like 2000+ calories daily, but I’m just not hungry and i can’t being myself to. In this moment i’m almost afraid of eating. right now it seems like previously i’d only been maintaining my calorie intake by eating excessive amounts of junk food, which is kind of unsettling.

I’m wondering if my body is having some adverse reaction to the loss of all the junk food or something? is this something that’s a thing? how should I go about upping my calorie intake on stuff that isnt terrible for me?
