Hi, so im really grateful for my height (thanks to my dad) but I am really skinny. 6’4 150lbs. I did do varsity swimming for 4 seasons around 4 years ago (pretty talented. out-swam bigger guys than me. But barely hit the gym during that time)

I want to get bigger. Being bigger is probably the most important factor. People respect you more, girls like big muscles, and you feel good about yourself. Ive actually reached a point that I dont want to get laid anymore due to my body. I feel I have a face of a 20 year old (especially if i had not shaven) with a body of a 15 year old (mostly weak chest and small arms).

But problem with me is that I try to lift heavy. I have been consistent with Stronglifts 5x5 (bench, squats, deadlift, barbell row, overhead press). But when I lift heavy, I often get dizzy and feel like I am going to faint. Therefore, I sometimes end sets early.

I feel this is because I am not eating enough. Which goes to my next problem. I dont have an appetite ever. I only know I am hungry when my stomach starts to hurt. I rarely get moments where “Oh [this food] would taste so good right now”.

Yes, I have counted my calories in the past and I even dedicated a day to just stuffing my face in. I hit 4000 calories that day but felt really shitty the whole time. If I eat a lot, I tend to feel really bad and get headaches.

Any tips? This problem is by far the biggest I have and I havent found any solutions.
