This is normal but you have to stop at some point or you'll end up writing a book. SS will send you a form stating that they need more information if they do. They will send you to their doctors and he or she will assess you. Don't try to look to good. Look how you feel. If it hurts say it hurts, this is not the time to be brave. If you get denied no fear you have a couple of appeals and if you feel overwhelmed, you have a right to representation, at the attorneys cost if you lose and they take it out of your backpay if you win.
