Dealing with Job Interview Anxiety

I have a phone interview at 11:30 EST this morning, and I am extremely nervous, yet excited. I haven't worked in 3 years because of the severity of my mental health, but I spent that time getting help and trying to stabalize myself as much as I could. No matter the help I got of course there's still that lingering anxiety that I have to deal with. Times have been tough and I really need the money so I'm trying to push myself. It's a work from home job and has to do with my passion. I have quite a bit of social phobia so I figured this could at least get me working in my comfort until I'm truly ready to get out there. At the same time I feel like it can make it worse and I may get too comfortable not having to face people physically. What a battle. I wrote down a bunch of notes this morning on the job and about myself to ease my way through any interview questions. And I'm hoping things go well. I almost always get the job that's never the problem really, however I always ruin the opportunity and either no show or convince myself out of it. I know this post is kind of everywhere, but I really needed to get it out my head right here.
