I'm so sorry to hear that! My condolences. I hope writing provides some sort of catharsis for you.
When I tried to download Brave it kept giving me the same security warning. Then about 8 months ago it stopped.
Do you use Linux, or some similar operating system? I use Brave on Ubuntu, and it works alright. :)
I use Chrome which had me frozen from downloading anything else. Then one day, like magic, everything went back to normal.
Something pulling you back here. Glad it did.
Thank you so much
