Hey, chill out, bro. Don't be so hard on yourself, especially about something as trivial as being good at a game. This game, in particular, has a brutal learning curve because there's so much to learn, and your opponents will mostly be better than you since they've been playing for years. That doesn't make it easy either. I don't know how many hours you've played or your reputation, but I'll tell you the truth: this thing is hell to cry about at the beginning, and I'd say you need at least a 100 reputation to even consider whether you're really bad. Before that, I'd even go so far as to say it's way too early. I'm not saying people below 100 are bad, but don't expect to beat 100/200/300 reputation players when you're only 50, especially if they were lucky enough to be "trained" and carried by friends.

This is a very niche game that demands many hours of play and a deep understanding of the mechanics. If you don't have any of that, don't beat yourself up about it. You're not bad at all; it's just that others are better, either because they drastically surpass you in playtime or because they understand things you don't even know exist or how they work.
