Step 1 (lol): Calm down
Step 2: Make yourself a schedule. It can be as detailed or basic as you like, but I recommend mapping out your 7 weeks and planning how you're going to get through everything. I think it's doable, but you have a lot of work ahead of you.
Why don't you have 20% of DIT done? I haven't used DIT but I thought the purpose was to go over FA?
My usual schedule at the beginning of my dedicated time was to study a chapter in FA, then do questions in that subject. I had already done Pathoma during MS2 so I would just read through the book/my notes as a supplement to reading FA. As I went through more topics, I started incorporating those subjects into my question blocks so I worked my way up to a block of random questions by the time I finished my first pass of FA. If you haven't studied specifically for Step 1 and you do a block of random questions, of course it's not going to go well, unless you really know your stuff.
Don't judge your performance on a block of 10 UWorld questions. UWorld is meant to be a learning tool, not an assessment tool, and doing less than 1/4 of the questions in a real block is even less of an assessment than a full block.
