I can say with total conviction that -yes people get better. I did.

What will never ever change, though, is life. There will always be ups and downs. Crappy things beyond our control.

What changes is the way we react to those crappy things.

Now, I'm certainly NOT talking about suddenly developing a rosy, happy view of everything. "OH! I lost my job - fantastic!".

What does happen though is those things feel less catastrophic. You can also learn to NOT pile everything on top of each other into one big overwhelming heap of badness. THAT is a horrible horrible way to live. You can learn to take each thing at a time and appreciate what you have. You can learn to not only cope, but thrive.

Getting better requires self-discipline, practice, and a knowledge of yourself and a rational view of your emotions/behaviours. You must invest in yourself with your whole heart. What is learned can not be unlearned in a day.

Having said all this "howling at the moon" and bemoaning life is normal. Allowing yourself to stay in that mode is most assuredly not.
