yes, I think that such feelings are actually quite common. I felt a sense of anger and betrayal, even, as peculiar as that sounds-- it was like there HAD to be a reason why it happened. I wanted something to blame.
I also felt very, very alone.
While that isn't so, it can sure FEEL that way when most of those in your daily life don't understand what you are experiencing, or that you aren't doing it because of poor mental health.
