Dont be overwhelmed by small things; try and see the bigger picture. Is your problem really as bad as youre making it out to be? The chances are there will be many people worse off than you. Instead of zoning in on certain things and panicking about them, put everything into perspective. Does this problem affect your entire life? Will you still be panicking about this in a few weeks or months time? If the answer is no, then its really not worth the worry.
