Help modding this game please

i just downloaded skyrim SE and i tried to mod a little bit because honestly thats all you do with games, playing on a pc, so i went to nexuz and i saw nothing helpfull so i went to youtube and i saw 3 videos and each of them told me to download a different fucking mod manager app or menu or fcking whatever, so i went with vortex and i tried installing just 1 mod wich was a master sword mod, guess what it didnt fucking work, then i went to reddit to look for any help and this dude had a post that was a "dummy guide" where i had to install like 15 fucking mods of only "fixes" and i was loosing it because none of them were of a single fuckass weapon so i didnt even finished the guide bcs i didnt even understand what i was doing maybe i need a fucking baby guide or a retard guide cus modding this game its so complex i feel mentally challenged.

So this is a cry for help if anyone can help me step by step on how to download the game, how it works, wtf are some mods even about, and a overall a 101 on how to mod this game i will be very happy if not then ill go back to mod rdr2, the game is sketchy af but at least i understand what im doing.

also im not trying to offend anybody im just despertate please help meeeeeeeeeee
