@Can't think of a name, I can identify with you in a couple ways. I experienced seven years of major depression, six of which were while I was a pastor, with two bad anxiety attacks near the end of my depression.
1. I can't emphasize this enough. God gave me psychological help to get me in touch with my anger and anxiety that were hidden in my unconscious mind. It took mental hospital professional people to help me uncover those emotions that I had buried until depression brought me down. That Christian hospital is Pine Rest Christian Mental Health on 68th Street in Grand Rapids, Michigan. I recommend it highly.
2. At the same time I was at the hospital, God taught me directly from his Word a pattern of praying that is not in the western culture, lamenting. More than half of the Psalms are at least partly lament, that is, complaining focused on the Psalmist's, usually David's, complaints in faith, not like the Israelites' unbelieving complaining in the desert but more like Moses', David's, Job's, and Habakkuk's questioning of God. It involves laying out to God your genuine emotions and seeking his gift of the real, lasting peace of Philippians 4:6-7.
3. At the end of my 8 1/2 months of lamenting 3 or 4 times a week, God gave me that peace, which has lasted almost 4 decades now, as long as I continue my focus on him. Once in a while, the stress level has built up so that I feel some of the depression symptoms, I ask God what I'm getting depressed about (he is now my Shrink), I persist in lamenting again, and he gives me his lasting peace and relief from the symptoms again.
4. If you know the circumstances about which you are anxious, you can begin lamenting now, but if you don't, get God's help through people. You might have to go to a few psychiatrists; I had two of them, who didn't help me, before I ended up in that wonderful hospital, where they use the team approach, which is the best way. However, you might be able to ask for the team that uses specifically-Christian approaches (they helped me a lot), because many of them think that it's enough for the therapists to only be Christians.
You are now on my daily prayer list. I will pray that God will relieve you of your addiction and anxieties. All my Christian love, Bruce Leiter.
