oohhhh true true! and the steroid inhaler plus the steroid shot you got also make her scared and more stress sensitive. steroids are natural stress hormones in our bodies that we need to cope with emergency situations, so no wonder both of you are additionally stressed out. with this i mean: cortisone (or dexamethasone you are probably being given or any other steroid) do not CAUSE stress. they RISE when you're stressed to help you cope (like HCG doesn't cause pregnancy, but it's rather a consequence of pregnancy).
this is why you are being given them, to help your baby develop faster. just that when you already have loads of them in your body, both of you are more reactive to additional stress you are getting!
so yes relaxation is the word, school is important for sure but your baby is way more important then that! and you're doing all the best you can so don't worry as much as u can!
and keep us posted, so happy you don't have to deliver her now!
