1. Investigate the cause. If you merely solve the symptoms, you may have to encounter the same situation repeatedly. If this is the case, it is far better to investigate the root cause of your problem.
Retrace the steps. Sometimes it may mean recalling your childhood in order to understand why you are holding on to certain beliefs. By removing the beliefs that put you in self-sabotage, you would be preventing more problems from happening.
2. Deal with one issue at a time. No one is born superhuman with the innate ability to handle everything that life throws. If you try to do too many things in one go, you may end up with not accomplishing anything at all. It is best to spend enough time on one before going on to the next.
Hence, make a list. From your list, rank the importance of each issue and tackle one item at a time. Keeping a diary or planner helps.
3. Don't sweat the small stuff. When something is not going to ruin the big picture, don't sweat it. I had a client who used to complain about being stressed with having a bad hair day. She was the wife of a wealthy businessman. And so she had the conviction that it was her duty to be always looking good and presentable. I pointed out that she had got far more important issues, such as an unfaithful husband, to address.
You will feel overwhelmed if you have been accumulating a pile of "small" stuff. Step aside to see if you can discern whether it warrants that much time and attention. Learn to close one eye to issues that do not really matter in the grand scheme of things.
4. Be flexible. While it is good to stand for what you believe in, too much rigidity can cause you to narrow your choices. You find yourself being able to see only one solution. In certain cases, you may even believe that there is no way out.
Flexibility opens up options. It invokes imagination. There can be more than one way getting from point A to point B. No offense to animal lovers but there is also the idiom: there can be many ways to skin a cat.
5. Ask for help. You will be amazed how one simple tip of just asking for help can do. If you do not ask, no one knows that you are needing assistance. You do not need to be a hero or heroine when you are really crumbling under pressure.
There is no shame with asking for assistance either. Those who genuinely love and care for you will want to lend you encouragement. Friends, family and relatives can be a source of strength. They may or may not be able to help you physically but they can be there for emotional support.
