I agree gdf....anger is exhausting. I am right with you on stepping back too instead of reacting. A friend of mine always gets upset with me for that (we are business partners and she suffers from PTSD so we fight like sisters sometimes.) When I step back instead of reacting, which is 99% of the time, she feels or I should say felt that I was abandoning her. She now understands that I simply want to take time to process instead of the knee jerk reaction. That way I can respond in a more positive manner.
The other thing that I think is hard for us a christians is that we feel guilty for being depressed. We have this idea that as christians we should always be happy. Scripture speaks of joy which is a totally different thing than Happiness. Ther is this idea that as a christiasn we are supposed to forgive and just move on. Unfortunately with the things that happened to us we can't just "move on" until we have processed and dealt with the abuses we suffered.
For me, the abuse has affected my relationship with God. That is the one thing, more than anything else, that I want to get back. Trusting Him again.
