How the frick do people gain weight???

So I started working out about a month ago. Mainly bc my fiancé wanted me to drink less and that wasn't fun so I stopped drinking. Well then I had a calorie deficit of like 6-800 calories a day from not drinking. I have been struggling to maintain 180 lbs.

I basically replaced drinking with working out so I've had some serious gains but that means I have to eat even more. And the more I work out, the more my metabolism is speeding up. I am eating 2900 calories a day, maintaining weight, but I'm burning through all my fat so I'm probably at a calorie deficit. Taking creatine and too so I've almost certainly lost some weight since I'm holding more water weight now.

Eating 200+ grams of protein a day, like 40% of diet is coming from fat and I've been trying to keep carbs low since it seems to be working for me. I feel like I'm always either stuffed or starving 24/7. I hate food so much right now.

Anyways, I went and got my testosterone levels checked just because my buddy on Sarms was getting his levels checked mid cycle. Testosterone is 1120ng/dl, free test 26ng/dl, shbg is 21 nmol/ L and albumin was 40g/l. My skin is all greasy like a teenager, I've been anxious and I've been fantasizing about fighting lately so that makes a lot of sense. My doctor says I have to do some other test to make sure I don't have cancer or some shit but frick that nerd, I'm the king of rdrama now. I'm going to have to buy new shirts in a week or two. All the sleeves are getting tight. Probably gonna buy those new shirts next week when I'm proving I'm Superman and don't have cancer.

Anyways !fitness, what do I eat? I need to maximize these gains but I need more food. I'm bouncing back and forth between "I hate food so much" to "I will murder whoever moved my protein shaker my body is eating itself and I'm angry about it" like 6 times a day at this point. I'm down to 12-14% body fat so I need to figure this shit out pretty fast.
