Hi -- I heard a research study report on National Public Radio, that came out of University of Gainesville, about helpfulness of phone therapy with and without medications. Phone therapy (and I think the research specifically mentioned CBT) improved people both on and off medications significantly.
You also might want to look into online counseling. I've found some sites that offer this. I (and I think quite a few of us on the Psych Central Forums) get a lot of coming here for internet support, especially the perception checking. I've used -- and sometimes still use -- the Burns techniques (though as consistently and dedicatedly as you!). Having other people offer perspectives that show me areas of my distorted thinking is amazingly helpful, because even with the CBT exercises, I have blind spots and might not notice them without other people's input.
In sum, perhaps you can find phone therapy or online therapy. I salute you in trying to get this help for yourself. I think you are on the right track! Congratulations on your progress, and my respect for doing this by yourself. Keep going!
