So I used to be a toplane main but then I switched to jungle because of "lane anxiety" (taking perfect trades, winning lane, wave management, etc.)
However, I want to relearn top lane because I just bought Giant Enemy 
from My Shop (156 RP). I still have that same "lane anxiety" and I'm too scared of feeding since I haven't played top in a while. How do you guys recommend getting over this? Custom games? Just play? Git gud?
Meep Man2 votesTop Lane is the rice fields, but if you are certain you will take this burden, I'll try to help.
First of all, mobility is key in Top Lane right now, and if you don't have mobility then you gotta have range. Thankfully for you, Urgot has kind of a mix of both, so he's ok.
Second of all, Top Lane is about playing much safer than usual right now due to jungle pressure. Getting as much farm as possible is key without risking your life by pushing the wave up. Early game kills are not needed, as they won't help you decide the game a ton. Jungle ganks are the only way to really guarantee a kill in Top Lane, so if you want a kill, signal for them. Plus, Jungle ganks reward enough gold to where they can help decide games and will provide the Jungler with gold to help gank much harder to gank lanes like Mid and Bottom.
Third of all, and most importantly, you are there to be a Pushing Engine OR Peel for the ADC. I'm not saying you're a Support, I'm saying that you aren't a Carry. Just support your team and help those who actually can carry get kills to increase their DPS. Trust me on this one.
