Hi robbie,
I didn't want you to go unanswered especially as you are due to go on holiday tomorrow.
Going on holiday can be stressful at the best of times, but combine it with the OCD and it pushes the anxiety to a point were it's difficult to cope.
You're extremely anxious and so are catastrophising. You're seeing all the things that could possibly go wrong however remote the possibility. But it's the OCD that's giving you these thoughts.
Try not to be too hard on yourself and go and enjoy yourself with your family. Once you're on your way I'm sure that your anxiety levels will fall.
I hope that you and your family have a great holiday at Euro Disney. Let us know how you got on when you return. Don't forget if you have access to a computer whilst you're away you can always log on to the forum for support from members of the forum.
Have fun
Trudy
