One cannot receive triage on the field of battle.
You need immediate help. Your entire family needs to goto a therapist who can intervene on behalf of your family unit.
Your discussions & disclosures with your family cannot help you to deal with your ongoing pain and emotional recovery. They can't help you heal. Your family is dependent on you and when your emotional state threatens their well being they are blaming you. It must be stopped, and the quickest way to get it stopped is to see a professional.
Also in addition to the actions inside your family, you need some intervention to help you deal with your past abuse at the hands of the priest. They would be the appropriate person t disclose your more private moments to.
If your family doesn't respect you, and continues to abuse you, then you must respect yourself enough to stop them. You must take your power back. Engage a professional and begin to unlock the doors holding you captive.
Good Luck ....Geoff
