I'm kind of in the same boat as you a little, maybe not as bad, though. As you know, I just got a new internship. I'm also taking a couple classes this semester. This means I'll have to be up and out of the house Monday through Friday. Coming back from break, where I had no responsibilities for a month, this is kind of a big jump for me. Especially since last semester, I took mostly online courses and only had to be out of the house two days a week. My professor has a super, ridiculously strict attendance policy to boot.

Right now, I'm taking it one day at a time. I'm trying to focus on the task at hand. I also keep reminding myself that this is only for a few months out of my life. Telling myself that something is non-negotiable also seems to help my anxiety. I'm going to class, period, end of story. I'm going to work, period, end of story. I don't think about the fact I'll be driving in rush hour until I'm driving in rush hour. One thing at a time.

PMS doesn't do too much to my anxiety, at least that I notice, since I"m too busy being really grumpy and irritable instead. A pdoc once suggested taking extra B-complex vitamins two weeks before my period to help anxiety symptoms from PMS. Maybe mention it to your doctor and see what they recommend?

Good luck with your appointments!
