Team work in wood 5

What am I supposed to do in ranked especially with team mates who are always tilted no matter what. Like I have been playing for years and the more I play the less it makes sense, like your at the bottom already so why are you so mad? It does not matter so much that you need to freak out. it is really hard on support because support needs the team to win. when I play lux mid, my main, I can carry easier and I do not notice toxicity as much. However if I am doing anything else suddenly everyone in my game is pissy. I need advice for situations like, getting camped, team mates feeding, and no objective focus. I also have this terrible habit of trying to save my team mates if I am not a carry. Is that bad down hear? Like I heard someone in a youtube vid say not to trust anyone at low elo with carrying. So I decided to play mid and jungle the two most important roles at low elo. I used to main ADC for a while but that is impossible as supports are unreliable and in general pot shots if they will pick a serious champ or feed. It really depresses me because I like playing all the other roles like ADC supp and top, but I apparently cant because it is to unreliable to carry from there.
