on fire

I have a lot of anxiety right now. I don't know how to describe what I'm feeling other than that it feels like my chest is on fire and the flames get bigger every time I take a breath. I get this way a lot, with other symptoms too but this being the primarily difficult one, be sure it gets hard to breathe..
I'm close to a year and threee months cut free. I hit my original goal of being one yearcut free.... Now what? 
I'm trying to remind myself that there is a goal beyond these smaller milestones, but its hard to find reasons why I'm not cutting.
I found my pocketknife hidden away in an old purse tonight while I was cleaning and it was a huge trigger. I haven't been so close to cutting in so long... I'm really glad that I didn't do it but with the anxiety come urges and I guess I just have to fight through the anxiety for now.
