Waiting for breast clinic appointment

Hi. Ive spoken to my doctor today about my breast problems. Its hard and has a dent at the bottom. My doctor said she would send me for a breast clinic appointment straightaway instead of seeing her first. I feel slightly better now i've taken the first step. I am worrying about a lot of other things too. Results, going to the hospital alone. I've had an ultrasound and biopsy done on my other breast 2 years ago, so im ok about them, but am nervous about other tests.
