Hi Dancinggods, welcome to PC!
I'm sorry hun, that's a hard thing to do to have 3 tots on your hand. Listening to you though, they're lucky to have you as a dad.
When I was raising my child, I wasn't diagnosed and I'm sure I came across as a monster because he's thought I hate him a few times. But since I was DX'd, I was able to watch and somewhat control myself, which is a plus that you have, the knowing of your condition.
All you can do is the best that you can in a loving way. And in them bad times when you're feeling bad, practice restraint, even if you feel like raging.
The best I can say is to figure what works best for you and go with it. Good luck sweety, I'm sure you'll do fine!
