Welcome to MS.
I am glad you have found this place of healing and support.
It is good that you have set very strict boundaries with your father. You know all too well the harm he causes and that he only cares about his needs and not the effects he has on others. I am sorry that you lost members of your extended family to whom you were very close. Sadly, they are not able to admit to themselves that you are telling the truth. However despicable, it is easier for them to make you out to be the bad guy than to admit the horrendous things your father has done.
Please do not do yourself the disservice of comparing your story to someone else's. The details may differ from story to story, but it is all bad. NO ONE should ever have experienced these abuses.
Take your time and look around. You do not want to trigger yourself by reading too many posts at one time.
At your own pace, read the boards and wander into chat. The lounge (chat) is open 24 hours a day though it isn't always populated.
We also have moderated chats called Healing Circles.
They meet on Sunday and Wednesday evenings at 9pm eastern time and one on Tuesday at 19:00 UTC (European and African time zone) which translates to 2 PM Eastern US time zone. The Healing Circle on Tuesdays is scheduled to resume in January.
Again, welcome to MS.
