you asked about shakes earlier. For you, drink them as much as you want. As a matter of fact, you should be destroying the dollar menu at McDonald's a few times a week! Double cheeseburgers are $1!!! Go get 4 of them and a couple small fries with a milkshake or something.
You don't need to really worry about eating too clean right now. You need to eat a LOT...a TON...and keep adding weight to the bar every week. You'll grow...fast!
Have you tried what I suggested about keeping a journal of what you eat and counting the calories and macros? Set a goal to get a certain number of cals/grams protein. When you hit that goal, move it up 500 or 1000 calories. You should always be trying to consume at least 2 grams of protein per lb. of bodyweight. Make sure you are drinking plenty of water too (no sodas or sugar drinks - WATER)...at least a gallon of water a day for now.
EAT! EAT man, EAT!!!
