I am having a really hard time breathing and I ' m scared to sleep . I actually had a legit doctor 's appt for my back / pain killers and it would have been the perfect timing but they called and told me they had to cancel but I could come in if I could make it in by 1 pm . My car was being worked on so as you can see , my life is never easy . My family said my papers from the IRS came in and they are forwarding them to me so that I can get the school loans I need .

What may be the reason why they did n't make it to the doctor 's appointment ?
