Perhaps something helped with one part of what you were experiencing, while the rest still felt unresolved. Or you tried an option and could not tell whether anything had changed. If you changed several things at once, it may have been difficult to know what deserved the credit.
An attempt can feel incomplete without having been pointless. Some improvement may matter to you, while still falling short of what you hoped everyday life would feel like.
After spending time, money, and hope on previous attempts, it makes sense to want more than another reassuring promise. You want to understand what you are considering, what you can actually evaluate, and what the terms are before you commit again.
The next option has to earn your consideration.
