Depression, as I'm in now, has always made me feel alone in a crowd. As I have been taking medication regularly, I'm pulling out of this - slowly - by starting with small social settings, fewer words than many, and a testing of the waters, if you will. I know that in the past (when I was not depressed) I didn't have these feelings; so I look forward to the days when I can be "free" to be myself again. I hope that's helpful.
