Okay, here's my first one:

I was feeling like nobody is going to miss me when I move. The specific situation was that I went to lunch with someone I worked with last year as a speech therapy assistant, and we invited along the girl I was training for my other job at the preschool. I kept telling everyone that they won't miss me when I leave. I am scared that I'm not important and haven't made that much difference, so basically it means that I'm not worth anything.

This is how I addressed it:

When I kept saying that nobody was even going to miss me, I made the assumption that I could tell what other people were thinking. Since I was pretty impressed with K, and she was taking the job a step further than I had done, and had so much enthusiasm, and everyone seemed to like her, I felt left out and in the way and figured that I didn't matter to anyone. But it wasn't their feelings really - it was mine. I am the one that I don't matter to. BTW, K doesn't seem to be taking my job afterall now, so it's back to the drawing board there. Now I don't think they are going to be able to find anyone who will have the knowledge and skills that I would hope for who is willing to work for what they are offering for that job. But people do seem to be glad that I'm still there for now. It's awkward saying that I will be leaving, but not knowing when, and there are things I want to get involved with and don't dare to start because I won't be around to see it through (hopefully). People keep asking me to help with things and saying that they are glad I'm still around for this, that, and the other. There are things I can do that will be missed and probably won't be replaced.
