The secret for a guy like you is LIQUID CALORIES
I started out just like you did crazykid.
Eating enough food to grow makes me literally ill. I feel bloated, sleepy, and sometimes even dizzy if I try to take all my calories as solids. Stop trying to EAT that much. Eat 6 or 7 good meals each day and load up on raw calories by DRINKING them. Move your carbs to your last meal. Last thing you do from now on before brushing your teeth before bed is to slam down a milkshake. I keep a bucket of bluebunny and a gallon of milk on hand at all times for those shakes. During the day, soda and cool aid are your friend. Do at least three whey shakes a day and mix them double strength. If that doesn't work, make it TWO milkshakes before bed. Investing in a juicer is a good idea too. Get those mega 5 pound bags of mixed veggies at walmart or sams for juicing. You can drink more carrots and green beans etc than you can eat. Drink the pulp too. Swish it around in the glass so it makes a slurry. Tastes like **** but it is the only way you are going to get enough food down your gullet. Believe me, I've been there.
Don't panic. It gets easier once you start growing. Your stomach and appetite will grow to match your needs.
It seems hard but you are actually one of the lucky ones. All you are going to have to do to cut is lose the milkshakes and move your carbs to earlier meals.
135#? I'll lay odds you are doing mostly machine and pulley work instead of freeweights. When I first hit the gym, I was 5'11" and 124#. Friends called me Skeletor. I didn't use FW because I couldn't. There wasn't enough strength to hold any type of form for more than 2 reps on most exercises even using those ***** 5# girl dumbells. I got outlifted by elderly women who were doing surgery rehab. I literally fainted from overexertion doing curls my second week (important lesson, don't hold your breath when straining.) Sound familiar?
Tell you how to overcome that. Ignore building size for awhile and work on raw strength. For upper body exercises, use a weight that you can comfortably do 10 reps on. Do those ten and immediately reduce the weight by ten and do an immediate ten more. Drop the weight by ten and do ten more until you do ten with just the bar. Next week, try starting out 5 pounds heavier. For legs, do the same except do 20 reps all the way down the rack. (Ignore anyone who laughs at you when you start whimpering like a whipped dog and keep pushing, down the rack on legs is going to HURT) In two or three months you'll be ready to take on the freeweights, only at about half the weight the machines say you are lifting. Focus on working big muscles. Chest (no flys on a machine - useless), tricep (pulldown - use the rope), bicep (EZ bar and STAND UP), lats (pulldowns - one set each with narrow then wide grip), quad, ham. You can't build strength anywhere else on a machine so don't waste one single precious calorie trying.
And don't give up. Not quite four years later I'm up to 185#. That's 61 pounds or over 15 pounds a year. You can be over 150# by this time next year if you drink some extra meals and keep lifting.
