Ajmaryott Sounds just like what my daughter is going through, and it sounds very normal to feel this way. She has had over a year of her own routines with no time constraints and control over all of her food and her bathroom times and places. She is also very worried about returning to the in-person school due to Covid. She has told me about some of her plans to try to manage her GI issues, so maybe this may be helpful for you. First, she said that while she is not looking forward to being back in school, she is working to embrace the "normal schedule" part of it, see it as a benefit; second, she has formulated a plan for how and when she will eat and how she will prepare for the week. Of course there will be hiccups in the plan, but having the plan laid out in detail helps to calm her anxiety about all of it. She has written most of her plans/schedule ideas down in some detail, which also helps to calm her anxiety/stress. Deep breaths, the belly kind, will help your parasympathetic nervous system to turn on and calm you, too, just in case you start to feel panicky. I wish you the best!
