Liz, help me out here but wasn't the route of taking the exam, etc your BF's idea? maybe i got the story wrong, but i thought you started working at his firm and he suggested you take the exam??
honey, take time and be really HONEST with yourself - don't let this be a choice simply because you feel you HAVE no other choice. that's like settling for a bad marriage.................been there, done that, got the t-shirt.
you are skilled and capable. THIS particular venture just might not be your THING. and it is perfectly OK if it's not. if you won't do it for yourself, I the great and mighty Anvil, GRANT you PERMISSION to change your mind!!!!
