I need help with weight gain and a good diet?

I eat really unhealthy fast food all the time and tv dinners when at home I don't seem to gain weight but I always feel. Well like crap. Drink sodas and not much water. I want to gain weight but want to be healthy. I have been feeling like crap for a wile like I don't have energy to do nothing and I get out of breath fast. I'm only 22 and weight 120-130lbs I wanna be 150-160 but stay healthy. I can't go to the gym dont have the money for that. Any info on a diet or supplement anything just let me know I wanna feel better for my new family
