Do you think you have problems? Someone has worse problems!
Hmmm, so I should be happy because someone else has worse problems?
No. But problems are inherent in life. If others can cope with worse problems then you can cope with lesser problems. Moreover, perhaps in some small way you can help the person with worse problems. Your problem is then instantly converted into a motive for good and in thus a wee bit easier with which to cope.
