Welcome to MS.
I am glad you have found this place of healing and support.
I am sorry your family is not supportive of you talking about the abuses you endured. Their notion that a priest would not harm a "good" person is distressing.
You were, and are, a good person. The priest did what he did to serve his own needs, and he gave absolutely NO consideration to the effects it would have on you. What he did had nothing to do with whether you were a good person or not. He did what he did because he was able to manipulate you and assure you would keep his secret.
Good people do not harm others in the way he harmed you.
You are not to blame for what happened. The blame resides with those who harmed you.
You do not say whether or not you are in therapy.If you feel therapy is an option, there are resources available. For help in finding a therapist please read the Consumers Guide to Therapist Shopping
. Psychology Today
has listings of therapists for all states and counties. You can choose the type of therapist you are seeking as well as the area(s) to which you are willng to travel. Also check your county rape crisis center. They offer services to males and females, at no cost to county residents. Some offer support groups in addition to individual therapy.
A therapist will be able to help you with the night terrors and the other fears you are experiencing.
There are several books you may find useful.
Abused Boys: The Neglected Victims of Sexual Abuse by Mic Hunter
There are also several books specifically about abuse by clergy.
You can find these titles, and others here at the bookstore
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.
