Solo queue is... different. If you want to play you should know in advance that a lot of people can't handle losing well, at all. So if you can handle flaming or if you're quick with the ignore button, you'll be perfectly fine.
Flamers aside, solo queue is a great way to improve your mechanical skill and your playmaking abilities, IF YOU CARE TO DO SO. But most people don't and aim only to win this or that match and thus fail to improve at all, blaming and flaming their teammates all the while.
It's also an amazing test and field of improving shotcalling abilities as getting 4 strangers to cooperate with you and follow your calls is quite tough.
I'd say put on your best fireproof suit and dive in. Don't pay attention to your rank, just play to learn and improve. If you happen to feed, apologise to your teammates, ignore the flamers and move on. Good luck :)
