I really need to get better dribbling with my left hand. And I've tried
Everything from 2-ball drills and tennis ball drills and none of them
Seem to be working. Can you give me some drills to help me and maybe
Some tips? I only have a couple of months before the season starts...
Thank you for your time. I really appreciate any help you can give me...

If this is so important to you, enough to invest some money, why don't you go to a physiotherapist and get some tips. He/she will tailor a programme for you which will benefit that dribbling hand. Otherwise, you aren't going to get that expertise here.

Some days if you can, practice with left only or mostly.
I would practice juggling 2 tennis balls with left hand. Or 3 balls, both hands, will help with Hand/Eye coordination also. Good Luck.

I am left handed. I was forced to learn to do certain things right handed because no one could teach me how to do it as a lefty. LOL so, I learned to swing a baseball bat and a golf club with my right hand. What you need to do is to start actively using your left hand for a number of other things , not just the dribbling. You are trying to get coordination control over the side that you don't use regularly. So, in addition to the things you are working on with the balls, start trying to use a fork and eating with your left hand. Start trying to write with your left hand. Start consciously trying to use your left hand for things that you would normally do with your right hand. If you play other sports like baseball & golf, start changing off to your left hand. It is hard, I know ,but if you keep on consciously trying to use your left hand for as many things as possible, it will retrain your brain and body, and you will eventually become ambidextrous (capable of using either the right or left hand for most tasks). Right now, your brain is automatically telling you that your right hand is the "right" hand. As a result, your left hand and arm are not as strong as your right side. So, go to a sporting goods store and pick up a hand grip exerciser. Something like what is shown on this link: Bodybuilding.com - Harbinger Hand Grip - Provides Consistent Tension! On sale now! (http://www.bodybuilding.com/store/gl/handgrip.html). Use it on your left hand. You need to build up the muscles in your forearm. That little exerciser will aid you in doing that and in forcing your mind to start getting better control over your left side.

Hope this helps. Let us know how it is going.

P.S. I wrote this and posted before I saw the other responses. I think Tickle's idea of consulting a physiotherapist is a great one. They might be able to give you additional tips.

When you practise only use your left hand, this worked for me.
