First Im sorry you had to go through that - and that your mother didnt support you - I am sorry that when she should have protected you she didnt - some people are toxic and we can lead better lives without them - but thats your decision -
forgiveness - thats a hard question -
I have forgiven my brother for the SA - but I havnt been able to forgive the guy who attacked me - its not in my heart to do so im afraid
I have said the words... but I didnt mean them - maybe some day
I think if it feels right to fogrive then do it - I understand why the guy attacked me - but I dont know if I will ever forgive him
and who will be there for your milestones hopefully the family you make for yourself and your friends - i think I may sound harsh - I dont mean to be - I think you need to take care of yourself and let yourself heal and live the life you deserve to live - happy and free

When you have come to the edge of all light that you know and are about to drop off into the darkness of the unknown,
Faith is knowing One of two things will happen: There will be something solid to stand on or you will be taught to fly.
