Anxiety..

Classes start tomorrow and I've been stressing about it all week. I'm trying very hard not to worry but it's impossible for me to control my anxiety all the time. It's especially bad right now.. I won't get any sleep, I'm sure.
I posted about my anxiety on the group for it but that didn't help at all.. I don't think it's right to dismiss someone's problems with a "its all in your head" or "get over it" type of approach. If it were so easy to turn off that would have worked the first time years ago, but it didn't. I don't think there's anything I can do to help with my anxiety except for take some prescription, but I don't want to do that. I'm not sure what to do.. I hate feeling this way all the time.
