Oh my dear....I'm in tears for your pain and worry for your aunt. I'm sending prayers to God for your family. For strength, for healing, for love.
My daughter tried suicide a year ago. She found help from a caring Psych. She is well now. Only focus your energy on your aunt, for healing and love. Do not spend your energy on the evil ones in this. They will have to answer for the pain that they caused. Hopefully your auntie will get the help that she needs to deal with this awful time.
PM me if you need to chat about it.
Hugs to you and your family
