Hardstuck iron 4 lp 0

Made my account a month ago and have been constantly losing my team the game since.

All the other iron 4s seem too good compared to me.

I have been watching guides and Videos of Thebausffs, but it seems that I fail at the fundamentals before getting the chance to apply the stuff mentioned in the tutorials.

I main Sion and keep losing all of my trades. My jungler comes to gank and carry me but I die and lose the advantage when I try to push to the 2nd tower.

I seem to be doing something horribly wrong judging from my results but I can't point out what it is.
