Was it a horrible thing to tell my mom that I was d?

I know without context the answer would probably be of course not... but I just told my mom over the phone. I was d half a year ago and never told my family about it. I just "took care of it" myself - went to the hospital and talked to the police and went to therapy for a bit. Well tonight my mom was on the phone and kept grilling me about how I always seem depressed and I just snapped and admitted to her what happened and I instantly regretted it. My mom is already emotionally fragile as it is. She started wailing uncontrollably and I couldn't stop her. I feel so bad... and the reason why I never told anyone was because I didn't want them to feel hurt by it. Was it a bad choice to tell this to my mom? I feel horrible to cause her such grief. If it makes a difference, I'm a grown 24 year old woman and I live thousands of miles away from my family.
