I eat around 2 cups to a can of honey roasted nuts a day?

i need to gain weight and i eat over 5000 calories...but it has been harder to eat that much food so i eat foods with more calories...i already ate nuts but only a little bit...now im like addicted and eat 1-2 cups or even a whole 12 serving container...and i also eat a jar of organic peanut er in a week and a gallon of ice cream a week...thats just additions to all the other foods i eat!!! BUT IS THAT SOOO BAD TO EAT SO MANY CALORIES OF NUTS IF I HAVE TO GAIN WEIGHT? I CANT STOP NOW AND I LOVE HONEY RASTED NUTS!.....oh and are fat free fig newtons healthy? i eat alot of those(as my other junk) but i also eat lots of healthy carbs, protein, fats, dairy, and all the healthy foods i need, i just eat lots of junk now with it...
