Tim Ferriss publishes a piece called Fear Setting. You might find that useful. Another suggestion is to actually write down and articulate the specific issues you're facing. I find that the act of writing helps me make sense of thoughts - much more so than simply thinking about my thoughts. Although I find I'm better at execution than planning so I like the mantra "just do it".
