Suspending my license?

First off, I will say that I am willing to accept responsibility for some poor decisions I made. But I got a letter today summoning me for a hearing in which my license may get suspended. The rundown: 2 speeding tickets, a reckless driving, and a "failure to stay in a single lane". The speeding tickets are totally my fault. The reckless driving ticket I got for a terrible accident I got in in which I swerved off the road to avoid hitting other drivers. I was praised by the other drivers and by the judge I faced in court for it for taking all the impact myself. The failure to stay in a single lane one, the cop thought I was drunk and when he found I wasnt, he gave me this ticket which I thought was a bit unfair because I wasnt drunk and he was quite unpleasant about it. He even said "I think your drunk, but I'm gonna let you go with this.".......So by his account he essentially let me back on the highway when I was "drunk". Anyway...I have a few questions. 1, is there anyway I can keep my license considering the circumstances with my wreck and the swerving incidents? 2, how long do they typically suspend your license for? And 3, I recently turned 21 a month after my last speeding ticket....does this effect my point standing? I have heard it "resets" after a certain age but Im not sure on it. I live in Colorado if that means anything. Thanks for any help anyone can give me. And please no rude responses.
