In one sentence, describe what the following article is about:

Even if you made a huge mistake, remember that everything is temporary. You might feel terrible right now, but this feeling will not last forever. Try to keep reminding yourself that the way you feel is only temporary and that should help you start to move forward. Almost everyone has had the experience of messing up something important. In fact, someone you know may have messed up something even worse, and this might put your own problem into perspective. Even if their experiences are different from yours, it will help just to talk, vent, and get things off your chest. If you are having trouble getting friends and family to listen, or if you’re unhappy with their responses to your problem, consider talking with a counsellor or therapist. In some situations, making a mistake may affect others, so you may need to apologize and it is best to make your apology right away. Think about whether your mistake was something that might have hurt someone else. If so, then prepare to apologize to that person. Try saying something like, “I am sorry for what I did. I realize that my actions affected you as well and I feel really bad about that. Can you forgive me?” Holding resentment against yourself will not make it easy to move forward either, so you will need to forgive yourself for what happened. You may find it hard to forgive yourself, but it should become easier with time.  Try writing yourself a letter that expresses understanding about what happened. Imagine that you are writing to yourself as a friend and be kind to yourself in the letter. Repeat “I forgive myself” as you go through your day. The more you say it, the easier it may be to believe it. You may have messed up option X, but keep in mind that you still have other options. Now you can explore those other options, and this process can be exciting. Make a list of new possibilities and courses of action. Allow yourself to dream about how rewarding the entries on your list might be. Planning for the future is a constructive way of moving on and it may help you to feel more in control of the situation.

Summary:
Put things into perspective. Reach out to your friends and family for support. Apologize if necessary. Forgive yourself. Make a new plan.
