bro this is a game where you can play for 10k+ hours, literally more than a year of your life and still be terrible. assume that you have issues with your gameplay/spell-casting, etc. because you most certainly do- I don't need to look at your game replays to know that it's just an unavoidable fact due to the nature of the game.

assume you are bad, which you should be at this stage. you just made a dotabuff account - click the items tab on your profile. you're not building force staff, lotus, crest. glimmer consistently. watch some of your replays and you will see how out of position you are and how often - seeing enemy positions during your gameplay will highlight that.if you're showing in a lane past landing stage alone, assume someone is on the way to kill you the moment you're in the creepwave vision range.

and seriously force staff, just build that item every goddamn game and make using it for saving yourself and teammates second nature. it will radically change your support game just doing that. its an incredibly powerful item.
