Tried and failed

I really wanted to ebf. I tried so hard. Pumping between feeds, eating lactation cookies etc. Now I am so tired. I don’t know how much longer I can continue. It doesn’t seem to increase my supply. I know my body is supposed to know what to do, but for some reason it doesn’t. Im crying right now. My husband is “depressed” because I can’t seem to satisfy my baby with my milk. I don’t know what to do. I can’t do this. I know fed is best, but why am I feeling like this.
