Feeling Betrayed

Has anyone ever had to have a ultrasound guided biopsy done for a lactating fibroadenoma? Please share your experience. I found out today I need to have one done. I’m freaking out. I just had a baby 2 months ago and I wasn’t able to breastfeed for more than 5 weeks even though I wanted. Last year around this time I had a miscarriage and I’m just feeling really let down by my body. It doesn’t seem to be “working”.
