since monday I have been very anxious about travelling down south next week. lack of appetite and sleep and agitation. But after a really relaxed night with friends talking about it and other things I feel really chillled out can worry burn itself out?
Good idea to get distracted from thinking about it, geordie. Try and find things to distract your thoughts about next week, anyhoo you'll be just fine.
That is what talking therapies are all about -discussing your fears and trying to rationalize them. It has worked for you this time so its something to bear in mind should you feel anxious in the future.
