Don't be to hard on yourself. We all have to learn those lessons, you're lucky you got to learn them on your first bow, and a nice cheap piece of wood too. Now you are ready for the next bunch of lessons :D :D Oh....and they never quit!!!!
You should see the first bow I built., lots of set, uneven tiller, whip tillered, and a huge ol hinge on the one limb, way under weight, but it still shoots many years later, and when ever I have a beginner around, that's what I let them shoot,it's the only light bow I have .
I don't think it matters toooo much if your bow is not perfect, as it is still the same for every shot, the consistency comes from your form and your arrows all being exactly the same..
It's a shooter, so well done, now shoot the heck out of it, while you build another one, now to get hold of some Osage !!!
Good luck with the disease.
