you using a left handed mouse? seriously most mice are ambi, but there are ones which are contoured for lefties and that may help you with the issue... Also what are the specs on your system as it seems the slow response time may be causing the issue... Also, if you don't like double clicking there are settings within windows which will allow you to single click icons.
I was being serious. Get a mouse which gives a good feedback to your finger, and to your ears.
There was a time when I used to triple-click, for similar reasons. I was thinking that either the first-second, or the second-third click will count as double click, and the remaining single click won't hurt anybody.
