I feel like a total noob.

I am trying so hard to make sense of the Keto diet. I have calculated the below macros but I still feel so lost. I hate to ask for help but I need to :/ I only eat fish and avoid all other meat and am worried this will be a tough diet to do this way.

Is eating fish and other things for protein doable? Carbs I get with the fiber deficit but 100grams of protein and 67grams of fat... I am at a loss as to what to eat and how to measure it all. I have read the FAQ etc.

If someone doesn't mind, would you mind helping verify my macros are correct? Really sorry to ask but need some guidance. Thanks for your time!
