Addicted to dirt?

So a while ago I started having very strong cravings for dirt. And I figured maybe it was an iron deficiency or something so I went and got blood drawn... and everything came back normal!!!! After about 3 months of craving dirt I gave in and ate a spoonful. (Ik it sounds disgusting but it's hard to deny cravings that last that long) well. 5 months later. I'm still eating dirt. And everytime I try to stop I just end up doing it again. Idk what to do but you guys are normally supportive please help... also please dont say anything negative because I'm hella scared to post this.
