How can I stop letting anxiety rule my life? It's anxiety that manifests in a physical manner and makes it impossible for me to do anything.

I always have anxiety about something. Typically about my head, heart, or currently, a toothache. About two months ago I was laid off from my job. I have been in the lowest of lows since then. I have no motivation, I half-ass apply to jobs, and just sit around being anxious about something. I want to go back to school. I want to work. And I want to go back to being the confident (semi-anxious) person I was before this.

I can tell my family and my boyfriend are trying to be supportive but also wondering when I'm going to get my shit together. I have no motivation to do any of the things I really want to do. I used to go to the gym frequently, socialize with friends, and care for myself. I want to have a purpose again.
