I manage to get out past the breaks, but once I'm there, if I'm too tired to catch an incoming wave it will toss me around like a rag doll. It's really scary, even though it's a bit of a rush too.
When I catch the waves, if I fall off too soon, the water is still really turbulent and I'm worried the board is going to slam into my head, or maybe I might get pushed under and hit my head on the coral. Also, as soon as I fall off there's usually another big wave coming at me, and I can barely get on the board in time.
The upside to all this is that it is easy to catch the waves

I know the best advice is probably to avoid this big stuff until I'm ready, and I think I will, but out of curiosity, what should a person do in this situation?
