Ellie, I feel bad for the situation you found yourself in and hope you can get past it. But what I dont understand is what type of training you recieved. Obviously you have some pretty substancial issues to work out and these should of been addressed before you recieved your certifaction. Besides your fears, issues concerning predive, dive,and post dive procedures all should of been taught and gone over in length. I think if want to proceed with diving you seek out more training possibly with someone more in tune with your needs.
