I'm so sorry that you are having an anxiety attack
This is a big decision, so you are wise to wait. Of course you can't make a decision like that until you feel more like yourself
But there are no wrong answers. Whatever you decide will be in your best interests because only you can decide what's right for you- not your therapist.
Is the Ativan helping at all? Have you tried taking it yet? You haven't mentioned it.
I hope you feel better soon
