I Want to Vent

I had a good job and I was enjoying it, my boss left the organization and asked me to move with her which I did, to move to a horrible Job, I tried to move back to my old job but I couldn't and now I am suffering every day and I regret what I did very much and that makes me not able to sleep sometimes I apologize for the story but I just wanted to throw it out as thinking about what I have done to myself makes me so Sad
