That's pretty impressive that you tried to learn guitar with your non-dominant hand... I'm right handed but I can't imagine learning how to play with my left hand. Sometimes when people find out that I play guitar they want me to play something for them... and I don't feel like it... so I play left handed to make it seem like I can't play at all. It amuses me. But anyway... I suggest simply learning with your naturally dominant hand. Everything will be that much easier. It shouldn't take long at all for you to catch up to where you are with your other hand. Good luck with it!
