I feel like I've lost myself. Ever since the weekend, I feel like a completely different person. Nothing has changed in my thinking, feelings, or behavior, but I don't feel like me anymore. Every place I go is familiar, but unfamiliar at the same time. It's almost like deja vu. I almost got lost this morning, on a drive I take twice a month. I don't know where this is going, but it's scaring me.
