Aww, yeah I feel like that too but mostly when I miss out on something. So for one, pat yourself on the back for going and not having the panic interfere/stop you. Second, it makes sense that you're anxiety would be higher than normal (as well as a decreased appetite) after a death in the family. Cut yourself some slack. As for another one coming ... worrying about having another one sets you up for another one, I know its hard but keep telling yourself that so what if you do? You've gotten through the 2 you've had already adn you'll get through any future ones. I know how hard that is, trust me, but it's also true. You can get through and by taking the pressure off of "Oh no what if I have another one" you will actually decrease your anxiety. Hope this helps, I'm sorry for your loss.
