To move forward or to find another route?

I'm overwhelmed with stress. Stress at work, stress with my fiance, stress with my family, stress with this long and sometimes painful journey. I'm so overwhelmed with everything. I know there are millions out there who are facing a much more difficult period than me. Yet, when I look in the mirror I only see the woman looking back at me with life's tiredness in her eyes.

I know that right now I'm actually approaching a dark and long tunnel. It's that time of life where I can decide whether to find another route or just keep on moving towards that darkness... and right now I'm standing in front of that darkness not knowing yet what to do.
