You’ve just got to loosen up, and it won’t happen if you try to do it all at once. Take baby steps now, but keep taking them — guide yourself gently but firmly. One thing at a time, and focus on what you’re doing, for distractions will only keep you from making progress. If something seems to not be working then look for another way to make it happen, or engage in preparations for it and hopefully that will help to get the ball rolling. Patience is what you most need right now.
