I have had /do have all of the same fears/concern as were voiced here. I am 52 in a class with a bunch of twenty - somethings.. I have to believe I have been chosen and chose this path for a reason. I have only gottentthrough the first quarter and have 8 more to go, but I got A's and if I didn't take the chance, I don't know what else I would be doing. It's a fresh start to a new and hopefully full filling career. I hope to leave this planet knowing I made a difference in someone's life for the better. Don't let fear and self-doubt keep you from taking this challenge . You know you have what it takes or you wouldn't have made it this far. BELIEVE!
