Have you or someone you know been diagnosed with anxiety disorder? I have it and it can be difficult even for the smallest tasks.
I do know someone. its quite debilitating  it is often accompanies with the feeling of fear.
Sometimes it can get so bad that even the slightest tasks trigger it, like opening emails. My sister had to spend an extra year in graduate school because of it.
wow, i now that you spend a lot of time worrying about the future.
