Hey Naomi! Welcome here! I was nervous a lot when I was teaching too 
Maybe you can get married in the summer vacations? (So there is less overall stress?)
A friend of mine had panic attacks before marriage too.. Went to psychiatrist and he told her it was normal.. Does the guy feel 'right' for you or do you feel you 'need to get married' (due to other things) maybe worth to think about.. ((hugs)) Hope things get better!!
