How do you bot lanes lose so badly?

I just don't get it? How do you die 4 times before I'm even done killing my second buff (third camp)?

Like, I get that you're squishy. I get that there's a support who's job may be to engage and set up kills. You died 2v2 once already though, that's fine you didn't know better. Once you're behind though, play like it - stay back and wait for your jungler and mid to come help you. Why are you going straight back out and trying to last hit every cs and trade and just dying again in 15 seconds?

There's this concept of giving up CS if it's going to cost you too much to get it. You guys really need to learn that.
