Cramps can go away, a rash could go away too but if you have a srtoke you must seek medical attention so it can go away.
So the answer is Heat stroke.
To leave and if you can leave call someone to pick you up
I had to do this too when i was in middle school;
Number 1, I said that their are many local gyms and fitness centers, healthy restaurants, and clinics that help your health, and one way you can say that you are experienced with one of them is by going to a gym or eating at a certain place before, or even shopping at a clinic.
For number 2, you can motivate yourself past and distractions by staying positive, paying attention by putting more focus on what your working on, eliminating distractions like your cellphone or devices, or anything that is unnecessary for what you are working on, and not letting others in the classroom or work environment distract you.
Good luck, hope this helps!! :)
This is true. you must consider this!
