The best way I know of to deal situations that make you uncomfortable is to expose yourself to them, often but at low intesity, and build up a tolerance. Start small, and as you handle each issue, you'll find yourself thinking "I've got this, can't be much worse than [x] that I did last week." I used to be a really heavy traveller, carry everything I could possibly need with me, just in case. I gradually whittled that down, and now when I get nervous about forgetting something when I pack, I just tell myself that so long as I have essentials (eg wallet, passport/ticket, change of clothes, netbook), I can fix everything else. So set yourself up with small stressful situations, know that you have a relatively painless way to back out of them, and talk yourself through it. Have faith that you can fix whatever situation you find yourself in. You may have to start out by lying to yourself in saying that, but as you try (and succeed) you'll find that yes, you can handle things. Even the ones that really worry you.
