Everyone, at least once in one's lifetime, shall go through periods of anguish, depression, regret, disappointment of oneself and, of course, very difficult situations that produce all the feelings aforesaid. However, what not we all have is the capacity to endure any situation. Ergo, they fall in some of those feelings. How to manage to face tough situations? If that question were easy to be answered, many psychological problems could be avoided. My experience has shown me so far that you must work hard on your problems, never avoid them, never pretend they don't exist, never postpone them. Embrace them and let them embrace you. Of course you can feel anger and exhaustion because of repeated problems, I mean problems that seem to never end.
On the other hand, every person has their own degree of tolerance, so it is possible to fall into depression or just cry, depending on that.
Just one last thing: this is my advice for those who are going through a difficult situation: surround yourself with people who make you feel happy, avoid negative or nervous people. That's the best way to recover quicker.
