Potty training 2 year old...

I know this has nothing to do with being pregnant, but my emotions seem to get the he best of me lately. We've started potty training my 2 year old son. So we don't have to have 2 in diapers. Not only am I exhausted all the time already, dealing with pee and poor every where just seems like too much at times. Esspecially when he does it on me. I know he doesn't mean to. He is just 2. But I totally broke down and cried after I had taken him potty for which he did not go. And then litterally just 4 minutes later he pooped in his underwear. Ugh.... My husband tries to help but he works as well. I guess I have 5 more months to help him to be a pro at using the potty. Praying for patience.
