I've been feeling the same way. I think it's been going on for awhile and I just blamed it on other things- I was too busy, I had recently moved, etc. However, now that I've taken a step back I go through feeling angry, sad, and then feeling nothing towards those around me. I've been home with my family for Christmas and it's been a struggle at times when I just want to be on my own, but then I crave being part of the family and feeling normal. I've experienced some depression and anxiety over the last couple of years, but I've been at my worst for the last 6-7 months. I know I need to be socializing to make myself feel better, but part of me wants to be left alone.
