I am Leftie also, I have an adavantage I think.
My Mom is a rightie, and Dad was a leftie too. I learned to use right handed things. Only thing I can't do is write with my right hand.
I do things backwards sounds odd but it works for me. I learned to adapt to a right handed world.
To this day I can't use things made specifically for lefties.
In my family...7 out of 9 of us kids are lefties. 4 of my children are too. So are 5 of 13 grandkids.
