Breast Cancer Support Group?

This may be a long shot, but I was told that I carry the BRCA-1 mutation at 18, meaning I have a very high chance in getting breast cancer in the future due to it being in my family for generations. I am now 24 and I struggle with accepting it, I talk to my mom about it a lot but it has caused me a lot of depression/anxious thoughts about my future.

Is there any support groups or anyone who is dealing with the same thing that I could go to?
