Looking for a new and improved me

Hi the name is sean I have juvenile diabetes I am 22 years old. I have always wanted two be a bigger guy but have a hard time gaining weight. I weigh 150 my goal is 185 before summer here in the USA. I am just going to start trying to intake about 4000 calories daily and hit the weights very hard and cut down on my cardio. I have always been a fit guy an stayed in shape but just tired of how small I am. #IgotThis
