Maybe it was just really shitty. Or maybe you did it wrong. Nevertheless, I think that you just need to stop being pissed off about how it didnt work and just take it as a sign that you shouldnt try to eat or drink weed (unless you know how to make butter) and just smoke the stuff. I know it sucks when you dont get anything out of it, but just learn from your experiences and smoke it up next time. Just like how people learn when they first start smoking, they learn what not to do when they realize that certain methods dont work. If I were you, I'd stop trying to be a scientist and start trying to get high.
