>What muscle groups do I have to work to increase the width of my shoulders?
Side delt.
>Is it even possible to widen my frame at all?
Depends what you mean by frame. Can you make your bones bigger? No. Can you make your muscles bigger? Yes.
Real advice: don't specifically focus on certain muscles if you're just starting. You're gonna fuck yourself up. If you do a normal beginner program, everything will get bigger.
>how do I stop caring about the opinions of others
Get a hobby. Fill your time up with so much of your own shit that you don't have time to think too much about other people's shit.
>Physical and Mental gains
Physical gains come from lifting weights. Mental gains come from doing things that aren't mindless. Even lifting weights falls under that category. You don't have to play chess or learn math, you just need to do something that doesn't let your brain go into pseudo-sleep mode. Don't play video games or browse /fit/ to fill time, they turn off your brain.
