Tomorrow is my radilogy exams...upper gi, u/s and chest xray

Tomorrow (1-14) is my upper gi, abdominal u/s and first set of chest X-rays.... I will not lie I'm a little scared. I'm going alone. I know it's no big deal but I'm showing high anxiety and my stress eat wants to kick in. I am on a fat free diet for 24 hrs.. Normally no big deal but my stress response is making me crazy. This is just the first few steps in my process. I have a surgery date of march 20. I've already done my sleep study, started small plate living, limiting soda, no fast food...

I have already started PT and tue is my first support group meeting. I kinda feel like I need a sponsor to talk me down or something...
