Drying up

I'm really down in the dumps. I have been ebf for 2.5 weeks now since my little babe was born and my milk is already drying up and I am taking it very very hard. I have been really enjoying it this time! This is our last child and I'm just feeling like a huge failure and feel like I'm still clinging to hope but it just keeps getting less and less. I have tried brewers yeast, lactation cookies, water, Gatorade, eating good, power pumping. Nothing's worked. 😢
