I need to build tear on anivia but do I start dorans or tear?

Does anyone have any resources to help me as a new ADC with wave management? I am constantly being told things like slow push, fast push, crash the wave, freeze the wave, get prio, etc etc, and I dont really know how to do any of that. Like I know to freeze the wave I need 4 caster minions, but there's only 3 in a wave? Any help, articles, videos, etc is appreciated!

Is there a set way of getting 10.0 cs a game I can't seem to get past 7 https://www.op.gg/summoners/na/Hylzos-NA1

I always miss out on cs and nobody comes to bail me out so how do I deal with them on my own?
