I’d like to invite you to join Script Abusers Anonymous
The only advice I have is mostly written over there, but suffice to say I had a similar experience and was at nearly 700 lessons, from using re-order scripts to level up without completing vocab yet.
Now, I make sure to get 0/0 before level and I feel much less pressure over all. Just take your average time it takes you to guru your radicals, divide the number of lessons by that and do that many every day.
