I'm on day 14 of the SEP and today I've been feeling a lot of "unexplained" sadness. I don't know exactly where it's coming from or what it's related to. I haven't really tried to figure it out either -- I've just been extra kind with myself and have allowed myself to feel whatever I feel. Is this relatively common and normal for someone doing the program? Have others also felt unexpected feelings coming up like this, even if you can't quite figure out the cause?
