You also need to eat more. Your sample day seems less than 2000 calories to me. One of the hallmarks of NLP is that, at your size, your weight should be going up consistently. Weight going up equals mass being added to your body, including (and predominantly, if you're doing it right) muscle.
Beyond that, keep in mind that it's ok for the weight to feel heavy. You are lifting progressively heavier weight. You should reach the point where the days it doesn't feel heavy are the surprise. Also, if you make sure you have the ability to add smaller increments (e.g. +2.5lb), that will help immensely with presses as they will stop progressing at 5s sooner.
