If you can't continue volunteering, take a leave of absence from that group for a while. If your job is keeping you tied up from any type of life, sit down with your employer and try to negotiate flex time, or see if you can take some time off to re-adjust. Remember, there needs to be this turning point in which you reverse direction and cease to get deeper under pressure. Fight the war within. Stress and tension are inward strivings and unease.
Stress builds and builds and builds.
It is internal, in your mind and emotions and causes anxiety, depression, worry, sleeplessness, anger and other negative emotions and feelings. For me, my relationship with the Lord is my only comfort to calm the battles within. I find much peace in the scriptures and prayer. Here's the pattern of stress. When the juggling act is overwhelming, stop, clean your plate and re-prioritize.
