maybe you are over-stressed from the bad experience of childhood.
you can try some method to relieve stress:
Relieve Stress – Go Intense
For most people, when it comes to stress management, they’ll want to use the most intense exercise possible. Going to the gym and hitting a punching bag for instance tends to be one of the best methods of stress management and control as it really lets you get out your anger and aggression.
Not into boxing?
No problem. An intense interval cardio workout or a weight lifting workout can work the same ways.
As an added benefit, when you exercise intensely, the body is going to release a series of endorphins, which are natural stress busters and that will help to put you in an elevated mood.
Lower intensity exercise doesn’t provide this, so it’s one reason to really crank up the intensity when you hit the gym.
Tune Out With Music
The next point to remember if you’re going to use exercise for stress management is that you should do your best to tune out the ‘outside’ world while doing it. Focus on your body, the muscle contractions taking place, as well as your breathing rate.
This is what will best help ensure that you are tuning out whatever is stressing you out – even for just a little while.
This temporary freedom from your stressors can be very invigorating and after the workout is finished, you may find that you feel more calm and collected and ready to deal with whatever was stressing you out in the first place.
Some people will also find that music really helps out in this regard, so that’s something else to consider. Listening to your favorite music during an intense workout can be one of the best stress busting practices out there.
