This is a great topic, Lauren, and I've often wondered the same thing myself -- is my anxiety caused by something physical, or some emotional trauma that I don't even know exists? I was raised by caring parents, was never abused, and I've never dabbled with recreational drugs (I tried a couple hits of a joint exactly once -- didn't feel a thing). Yet I've had anxiety problems almost my entire life, although I've only been experiencing the worst of it in the past 3 years off and on. I literally woke up one day and felt like I was in some kind of strange fog. It was only last year (after two horrendous battles with it) that I discovered this was DP/DR. I've been torturing myself as to why this is happening to me, and I've never been able to come up with an answer. I tend to think that in my case, it's a physical predisposition. But if so, why did it all come crashing down on me when it did? For so long, I was creeped out that there was something wrong with my brain -- a tumor or something. If that were the case, though, it wouldn't have come and gone as it has. It's strange -- it seems to only happen when I'm alone or not actively involved in a conversation or some kind of activity that requires a lot of concentration. I typically like to be alone, but I'm actually looking forward to being around other people, because maybe the feeling will lessen. I guess it's because when I'm having a conversation with someone or doing something that requires effort and thought, it forces me to think about something other than my own sanity (or lack thereof). I'm just so grateful that I have an appointment with my therapist on Friday. I don't think I could handle it much longer if I didn't.
