There are lots of words that I could use here. Flummoxed, Stuck, Perplexed, Lost, etc.
But is there a word or short phrase that actually means (or is a good fit for): a situation where in attempting to solve a problem, due to a lack of understanding, big-picture-clarity or knowledge-of-subject-specific-terminology, you aren't yet able to articulate/express the problem well enough to effectively seek or ask for help?
Person 1: Why don't you just google it?
Person 2: Because I'm still [fundamentally stuck for reasons I don't understand and can't explain]
I have a few perfectly cromulent Geordie phrases for this but they are little known, and not appropriate for polite conversation.
