Can you recover without a support system?..... Other than blah or angry or fear, there is nothing to feel.
I think you can recover without a support system but it certainly helps. A support system can be a friend or two who understands what you're going through, or an on-line group like this. I have nothing but this site and AA, where I don't talk about CSA, just staying sober. But at least its people.
Feelings? Well you named a few: Anger, Fear. Add pain to your list and you've got enough feelings to work with. Happiness? Haven't felt it for years so I can't help you there, but I know it exists.
