I have found that writing helps me immensely. I don't mean on public forums or anything like that. I mean a personal journal, a place where you can write down what's bothering you, possible solutions, how you feel, rant, vent, what have you. I've used this tool since I was a teenager & it helps me break down some of the barriers I have when I'm actively thinking about the problem.
When i write it's like my brain shuts down and just lets my fingers do the talking.
Maybe if you write down your thoughts and fears you'll discover, way down deep, that the solution isn't as difficult or as far fetched as you had feared.
