What to do what to do...

Yesterday my trainer was here to find out what is going on here at work. I haven't been selling enough products (in his opinion). He is also the insurance guy for the business and he said he's been doing this job long enough that he knew there was something else going on.

I broke down and told him what was going on around here (without using names at this point). I told him EXACTLY what had been taking place and was was now taking place. My suspicions of being looked at are not suspicions. I was approached yesterday and asked...

Friend of mine: What is going on between you and employee?
Me: Why?
FoM: Because he came up to me and said, I just want to set the story straight and want you to hear my side of what is going on....(and precedes to tell her that he has done SOOO MUCH for me and now I turned my back on him).
Me: Oh really.
FoM: He also wants me to ask you what he did to you that made you go to GM?
Me: Well, not to be rude, but I don't think he should be going around to people like this. We are not in highschool anymore. I had NO Plans of discussing this outside of GM's office and I am going to leave it at that. Now that explains why I am getting this feeling all over this place that the people are looking at me. Heck, KL hasn't even spoken to me this week and usually is in my office a couple times a day to bs. But then again, she has been at "the employees" desk quite a bit so I am sure he's filled her full of lies about me.
FoM: Well can we talk?
Me: Ok.
FoM: "The employee" ...did he ever follow you to your car? Did he never take NO for an answer?....(She goes on to tell me EXACTLY what the employee has been like towards her and it is EXACTLY what he was doing to me).
Me: You NEED to go to GM. I feel like people think I am just causing problems and after what you have just told me, I know it's not ME! PLEASE go to GM. This guy has a SERIOUS problem.

We'll see what happens. My trainer, let's call him Stu, asked me point blank what I wanted him to do to help me out. I told him I wasn't sure what he could do. Knowing now that my feelings of being "watched" around here are true, I'm not sure what I want to do. I really am stressed out beyond belief. I am going to apply at Walmart. That's how bad it is here. I worked retail thru highschool and college. I've been in customer service ALL MY LIFE. I'm going to tell them this is what I am available. Do you have anything that would work for me? If not, I can stay here at my current job until I find something. I just really think for my own sanity I need to do this. I need to get away from "the employee". Why do I have to be the one to quit though? I did nothing wrong! And yet, he is the one spreading the rumors about me! He's 50 years old!!!! Grow up! I don't know how to fix this problem that I got myself into. Now I think back and what if I had said NO more times. What if I had not let him push me around? What if I had went to GM sooner? What if....what if....what if...????

Why do I let myself think this way? Cause it's human nature I guess.
