Life can bring us down from time to time. At some point, you may find yourself in what you will consider as your darkest hour. As you try to find your way out of that bad situation, you should try to remind yourself that there is still a reason to be grateful.
If you look at your situation now and compare it with someone who is in much deeper trouble than you, I am sure that you'll find something to be thankful for. We all have our share of problems. But complaining about them so much only makes us blind about the fact that there are the miracles that happen around us every day.
When all your needs are provided, then you should be content and happy. If you have a roof over your head, some decent (得体的) clothes to wear, enough food on the table, a comfortable place to sleep, clean water to drink and you are free to make your own choices then you should be happy and grateful. Many people all around the world, especially those who are at war or those in very poor countries would give anything to be in your conditions.
Even if you lose all your money or possessions and your heart is broken for some reason, as long as you are still alive, then everything material you have lost can be regained again. If you have a few good friends who will be there to support or help you, then be glad because true friends are hard to find. As long as you have someone to love and someone to love you back, then you are a very fortunate person. Remember to be patient and trust that things will get better.
