Personally (keep in mind: only saved for 3 years), I've found that admitting that I've come to the end of myself and asking God to will to provide what I need to lead a life pleasing to Him is a good way to go. I was filled with bitterness and rage; now, I'm not. I was a lot of things; now, I'm fairly normal and growing in Christ. There is no complicated psychology behind it, at least not in my case. Its Christ's work in my life.
For me...its all about remembering: "It is no longer I who lives, it is Christ who lives in me." Speaking as a former angry person diagnosed w/ Narcisissism...that's challenging, but its also been one of the most important parts of the faith for me to begin to wrap my mind around. Less me, more Jesus. Of course, I don't know how to consciously pursue that, so I pray and try to move forward, day by day.
That's about all the advice I have for you. Again, welcome to CFnet.
