I am always alone. I went to a conference (vegan) yesterday and there were a number of folks I knew who all went out to dinner together afterwards and I was not invited. This is typical. I never seem to be part of the "in" group and seem to be avoided. I have been diagnosed bi-polar and have been hospitalized a few times but my meds are finally working. I feel like I have no close friends and my sister and her family are not really family any more since my going vegan. I am 73. I feel awful. Help.
