I think many are sincerely trying to get better, they just don't know how. I went to therapy for years and took dozens of medications all to no avail, though the meds did help my depression they did nothing for my anxiety except give me a physical dependence on benzos. I felt hopeless, the common treatments had failed me, I had to find another way.
I had developed some insight into the problem, but didn't know how to treat it. My problem is trying to be perfect, trying to mentally control the uncontrollable, ie the future. Worry is the ego's attempt or wish to control the future, it wants to control everything by finding a perfect solution. Worry goes round and round because its impossible to find a perfect solution to a problem.
I once read in a book that addicts are egomaniacs with an inferiority complex. We have much in common with them, they are just trying to avoid pain or control their emotions. We are all addicted to a perfect self image, or the pursuit of a perfect pain-free future. For what is anxiety other than an attempt to avoid future pain? If the ego didn't hold these things in such high regard, mistakes would be ok. It would be ok if people didn't like us, or we made a fool of ourselves. We wouldn't have feelings of terror that something terrible might come to pass.
So what have i learned from all this insight? To humbly accept most things are out of my control, for humility is the enemy of the ego. I've learned to turn my problems over to my Higher Power, I work the 12 steps of Emotions Anonymous. I'm not cured nor will I ever be, but have experienced moments of serenity even in the midst of benzo withdrawal hell. Turning to God was my last resort, I bargained I would do anything to get better while I was at rock bottom in the hospital. All I have to do though is believe and give up my ego. To the extent I do these I will get better, and I realize the only thing keeping me ill is myself.
