Talanic, I am sorry to hear how distraught you are.

Work with the pdoc. See what they suggest. There are different levels of EST so info will help allay your anxiety.

But the situation you describe sounds very serious and something must be done to try to stabilize the cycling.

If you want to try first aid, would suggest yoga or exercises to generate energy and a stronger presence in this moment. (youtube adrienne complete beginner yoga 20 minutes) or even Yoga in a dorm room can be done on a bed and chair.
