I punched and dented my door because I somehow gained another 2lbs. I don't understand why this keeps happening

I know muscle weighs more than fat and I'm most likely gaining muscle because I'm pretty much eating next to nothing everyday and going to the gym for an hour/hour and a half daily. I can't work my arms right now due to something being wrong with the muscle in my left shoulder so I've been doing cardio, legs and abs. I really don't get it and it's making me really mad and frustrated.

Nobody is going to want to be with my fat ass at this rate. I'm never going to reach my goal of 110lbs and between a size 0-4 at this rate. I don't know what else to do. They're not gonna give me ozempic because im not diabetic and it costs too much out of pocket. I don't know anymore. I'm beyond mad.
