On the Bulgarian squats, your forward leg needs to be farther forward so that when you squat down, the shin is almost vertical.
I also did my Bulgarian's in my power rack. This allowed me to get my balance first as doing so allowed me to grasp the rails first to balance and then I let go and boom - I was able to get them done much better.
