So today I finally went to the gym in order to see what it's like but I had no idea what I was doing. I tried lifting, but the only thing I managed to lift was the bar without any weights. My hands are shaking as I'm typing this and I can barely lift them.

I'm 17, 179 cm tall and 100 kg overweight. I don't know if I should go back after the pain stops or not, I don't even know what the fuck I'm doing with my life. If you've got any advice I'd be happy to take it.
