Many years ago I was part of a friendship group with co-workers. We went out for meals and generally socialised well together. Unfortunately it soured after I arranged a weekend for one of the girls big birthday and after a few drinks I overheard them talking unfavourably about what I had arranged and they had each spoken disappointingly about something that had happened, for which I was not aware and had no control (it was about another of the friends).
The result was it made me feel very anxious and I was left feeling poorly. I should have just gone home, but I didn't want to ruin the weekend, even though for me it was ruined.
Fast forward a few months and I suffered with depression as a result of bereavement. I received no contact or support from them and was criticised for not blocking them out and not making an effort with the friendship.
When the birthday girl got married, I was not invited to the weekend break but travelled an hour to join the group for a meal, unfortunately they were all hungover and decided to return early to the accommodation. I was not invited with them so drove (an hour) home.
The birthday girl became very ill and I would visit her as often as I could and post cards to her. She thanked me at the time and said how much she appreciated the effort I made and how it had cheered her up.
I was so disappointed in them, that when we all moved jobs I kept very loose contact via FB.
I have now found out they have met up and not invited me. I know they have treated me terribly but it still hurts that they are posting what great friends they all are :-(
