I can feel that.
I too get it sometimes. Through work I'm over it but sometimes I go back. What works sometimes is
-confront my mind telling it, you know what people like me and you are simply ignorant
-going the opposite direction and celebrating, saying to myself something like yay no one likes me how much fun
-invoking the voice of a grandparent saying something sweet
-going for the big picture and imagining the people who have indeed love me through the course of my life...
I hope it may be of help...
