B to R,
I can talk about two techniques (maybe there are really three...) which I have used at times.
One is simply, prayer.
If you can open yourself up to God's presence merely by being still (and you can do this when alone, or just in a rather non-invasive environment) then you can experience a connectedness that does not numb you; it is not any kind of avoidance behavior in my experience.
Particularly, include prayers for your own sanity/clarity, and prayers for those you love or care about. If you can do it (and at this point, I can't), you can even include prayers for your abusers. These need to be prayers for outcomes that you earnestly wish; if you earnestly wish the abuser's early demise, it's better not to pray for that. If you can pray for their soul, for their own healing, it can pay off for you in a surprising way, because it is a way of learning to defuse anger and replace it with a supplication to God.
A nun I met, who was in a contemplative Christian order, told me that there is a technique called "Waiting on the Name of the Lord" that is a contemplative or meditative technique that members of her order practice. It is similar to reciting a mantra from an eastern religion like Hinduism, or like using a mantra from one of its newer outgrowths like TM/Transcendental Meditation.
This technique, whether you use one of Christ's names or a mantra you have been given, or any other word, is just gently repeating the word pattern to yourself, while silently sitting and allowing your breathing and motions to settle. When thoughts come (they may be feelings, phrases, images, sensations, insights silly or profound) after acknowledging the thought, gently return to the word or phrase and continue to settle again until the alloted time is up. If it is some kind of withdrawal into a more quiet than usual state, well, it's only 20 minutes once or twice a day.
There are 'waking' meditations as well. 'Mindfulness' practices can be as simple as taking a walk in silence, whether alone or with a friend. No matter what technique you use, and there are many, it should help you add calmness and clarity to your day.
Even though I pray to a Christian God, if I had to say what religion has the most insight into the human condition, I would say Zen Buddhism. Dr. D. T. Suzuki wrote a wonderful set of introductory lectures on Zen. I also like John Cage's books, especially "Silence" and "A Year from Monday" for their Zen insights and wonderful stories. Zen has its own ways of dealing with thought...and can make meditation quite unnecessary.
