Feeling paralyzed

There are a couple of things I need to take care of ranging from returning phone calls to cleaning up some loose ends with work.  There is rather a larger issue I need to deal with involving finances and these things weigh on me heavily.  I wake up and think about them, even try to figure out how to handle them, but for some reason, just don't think I can do it.  I try to convince myself it's not so bad, I can do it, just do one and maybe the others will follow, but then I start to panic, really panic and just want to crawl back into bed and hide.  I know rationally that if I just dealt with the issues, then I would start to feel better and lately I've been feeling like more than anything else I want some kind of a fresh start, but I just don't feel "strong" enough to take care of these things.  And it scares me.  And I feel pathetic that I can just "get it together." I know from reading and past experience that it takes a while for medication to kick in; that you can't just "will yourself to get better", that  it has to take its course.  But I am scared.  What if it doesn't work this time????
