Do not panic, it's going to be fine.

Firstly, wipe your tears because men do not cry.

Why are you mad? Are you mad because you suspect the enemy player is cheating, mad because your teammates are trolling and you want to win the game, or are you just in denial about your lack of skills and coping by just being a keyboard warrior and being a nuisance to your team and the enemy as well?

If you suspect the enemy is cheating, or if you plainly know that they are because they are spinning faster than your head after you get up suddenly from your chair and headshot you even before you can fathom the idea of peeking them, this can go down 5 ways.
1. Crying
You can cry about it like a baby to your team and beg the enemy to kick that cheater (they won't)
2. Fight
You can install cheats yourself and have an honorable fight in the middle of mid like 2 autistic children fighting over their parents' love (they don't get any)
3. Flight
You can abandon the match, let your team surrender and then queue for another match after 30 minutes, or 7 days if you have done this before multiple times (which seems like you're coping for your lack of skill).
Or you could just go +right (or +left if you're a gigachad)
4. Report the hacker
This won't work but hey, atleast there's an option to report right?
5. Tryhard (respectfully)
Basically you're a black muslim trying to survive in London (you can't). So you can try and try and try but still get beaten by the hacker.

Are your teammates able to afford skins but not decent microphones? (They literally cost 1 dollar).
Are your teammates silvers who have been boosted by a dumb kid who hacks all day?
Does your team have 2 people constantly blaming each other when they die?
Do your teammates want to relax and treat a ranked game like it's unranked?
Do your teammates want to derank and take you down with them?
Do your teammates think the enemy is cheating while they're actually really good and now you have a team of throwers?
Here's what you can do:
1. Try your best
It is not just a game, this is a ranked match and you need it. Try your ass off. Try to ace every round, bait your teammates because they're no good to you anyway.
2. Scream at your teammates
This will release your pent up anger.
3. Try to reason with them
This will do you no good but hey, atleast you tried.
4. Start scouting
Find people who actually want to play seriously and you will eliminate this problem. Good luck finding randoms though.

Sometimes, your enemy is just better. They may have better hardware and peripherals, more hours in the game compared to you, has actually warmed up before the match, knows the map more than you or even just more skilled than you. You have to accept this. You are not the best player this world has ever known, and that is fine. Grow up and accept the fact that there are people out there better than you. It's okay, it doesn't matter. We all like to kill players less skilled than us and think that we are professionals at this game. Just take a deep breath and move on.

Stop being so toxic. Hate is easier to spread than love, so are you going to take the easy way out? Screaming at teammates and threatening them about things you have done to their mothers just proves you're a sad virgin. You can't do anything to anyone because they're in another part of the world and you're just a weakling trying to wage a war over a 45 minute match. You just annoy the enemy team as well as your teammates with your whiny voice and incorrect grammar. Maybe if you stopped taking loads in the mouth you wouldn't be so salty about a game huh? Stop trying to be a wank-stain and actually try to be positive. If your teammate misses a shot, instead of attacking him, say something along the lines of "it's okay man, happens to the best of us". Trust me, they will try more after listening to this instead of your usual "you can't aim go uninstall the game" We all have bad days, but it doesn't mean people should suffer because of your foul mood. Let me simplify it:
Treat your teammates like you want to be treated. The word teammate has TEAM in it. Be kind.
