Lost it

I'm taking a 'break' from school this summer but still taking 2 online classes.  I'm back east with my husband for most of the summer too.  Suddenly I find I've lost my confidence.  I don't know where it's gone.  I'm wondering if I have what it takes to make it through the end of this degree.  What have I learned that I can share and teach others?  I'm certainly no expert at anything!  What if I try to work in this field and decide it's not really what I'm cut out for?  I swear I was braver when I was younger.  Is that because I know more now?  Maybe ignorance really is bliss!  I want to be the self-confident woman who doesn't worry about being too old, too slow, too white.  What I need to do is dive.  There is a homeless shelter right around the corner- what is stopping me from helping out there while I'm back east this summer?  Just myself.
