I sincerely believe he said that for you not t stress yourself and also for you to know he cares whether you pass the first time or not. your anxiety is giving you negative thoughts, don't allow that to happen. stop stressing about it, you can do it, you are a strong woman and for you to have come to this level, trust me, you can even move higher than that.
Don't let the mountain move you, move the mountain and bring it to a low land, yes you can. best of luck.
