Just wanted to know if I was the only one whose like this.
I hate socialising - I hate making plans as I then fear and dread the day/time before it happens worrying about it like it consumes my life. It makes me quite grumpy.
However 9 times out of 10 I actually feel better for it and the grumpiness magically vanishes. 
I want to jump back into my own cosy bed afterwards and feel mentally drained but I've had a good laugh and really genuinely enjoyed myself at that moment.
But then I find myself dreading the next meeting with friends I have planned for.
I've always been like this even at school and through university.
How do I get out of this pattern as I do tend to cancel plans as the dread really gets to me but I want to be more social as it makes me happier as a person.
