i lost all hope in botlane (leaving botlane forever)

any other role is more fun and depending on yourself only i dont have lot of friends playing support, and they are not online all the time to play with me if i have just ( normal ) support, i win the game without any effort just with normal support, not even pro but most of supports that joins with me, Either doing nothing whole 10 minute just watching, or sacrificing too much to div them lvl 1,2 behind minions. i sometimes stop moving and just, im serious what are you doing? i really i swear i can't believe this im thinking are you picking support for joke? lot of things happens, lot of things for real, and it keeps happening,

1. support not giving hand on helping minions or even poke enemy, makes enemy adc farming like machine, and enemy support keeps poking me like im useless like im handless. and i cannot do smthing with this.
2. support sacrifice too much keeps going to enemy like they are nothing enemy full hp and still going hitting them so bad and just once we died it became even harder, with more sacrifice enemy adc will be unstoppable
3. support with no vision, when i play support i take zombie ward my first option in mind, and when i get back to base for once i get 2x control wards making my lane 100% vision clear all the time, and making adc Wards Allowed to been putted on the push.

i m very lost hope, i m very disappointed i almost liked Varus as a champ, and got S+ with him and S many times even before lvl 5 but now im very lost, i m thinking to not play adc anymore, cuz this happens before a lot and its happening again.

i will leave botlane forever, unless i join with a friend. Also i forgot, i thought we are one team, but most of partner in botlane is toxic, and negative. when you try to say something will be useful for both of us, he take it as a harass. so sad :( bye bye botlane you just make my nervous everytime
