If I may chip in...I've long legs and a tendency to go forwards.
So:
1-Put the bar lower if you can, this puts balance in a better place (grip has to be wider than shoulder width)
2 - Push through the shoulders
3 - Lots of hamstring work
And
Keep trying, but stay comfortable. Get a spotter, slowly build up weights, don't force yourself. I had it too and now it's gone.
