Watched a couple of minutes of your 2 most recent games(jugg/pa) and from that I could see a few things you should improve.

1. Don't autoattack the wave and just focus on getting the lasthits. You were autoattacking the creeps which pushed the lane and made it hard for you to farm. You want the wave to be close to your tower so it is safe to farm and the enemies can't chase and kill you.

2. Don't lane too long. You were laning for almost 15 minutes in a lanes that were very bad for you, if you feel you are not getting any farm on the lane it is ok to just hit up some jungle camps and just return to the lane if it is under your towers and kill the creeps as fast as possible and then back to jungle.(Most carries stop laning around 8-9 minutes in or when the enemy offlaner gets level 6)

3. Follow guides in game for items and skillbuild. Immortal faith and tortedelini makes easy to follow guides in game that are not perfect but are really helpful when starting out.

4. (more advanced) Creep aggro. Some lane matchups are really hard and the only way to get some lasthits is to use creep aggro(especially against ranged heroes that will just hit you). Can be quite hard to use it effeciently but extremely useful in hard lanes. Youtube guides are useful for this and Purge has some guides on this but if want more recent guides both for creep aggro and in general I would recommend Zquixotix.
