Well, Yurt...I think that getting out of town with some enjoyable other plans is an excellent starter. That is what I would have suggested, first!!
My second suggestion is to have a list of positive affirmations to replace the negative (future trippin') thoughts when they emerge. I feel that they MUST be written on an index card---for fast retrieval...as they do not come naturally in the face of fear and anxiety.
What we think,...our thoughts,...trigger feelings. Change your thinking=changing your feelings.
I would suggest that you start with the most scary future tripping thoughts---then write the positive flip=side of that thought to "neutralize" it. I think you get my drift....
When applied diligently, this tool is very effective.

p.s. Meditation is also very effective in stopping unwanted thoughts and anxiety. Very simple and easy to do. You might want to look into that for use, in general. I know that there are several people on this forum that are experienced practioners that could advise you.
