Stress is inevitable. It is our reaction to change no matter how big or small. What we have to try to do is not fall into the trap of constantly being stressed out, i.e chronic stress. One way to handle this is to be mindful. Sometimes we are so busy going through life that we react without stopping to give thought to ourselves and well being. This is why a meditative practice or regular prayer is helpful.
Be mindful and engage in positive self talk.
Remember, you are worth the effort.
