Why am I so anxious?

I told you all I was going to start meetings again on Saturday, but it didn't happen. To go to meetings on Saturday, I'd have to miss yoga - and I love yoga - so that day of the week won't do.

I was going to go last night, but I didn't get out of work on time.

So...just to get it over with, I'm going to a meeting tomorrow morning. Wednesday won't be my weekly weigh-in day, but at least I get the traumatic first meeting over with.

Yes, I said traumatic. No, I'm not being dramatic (well, maybe I am).

The first meeting is always stressful, there are things to fill out, things I'll have to remember to take with me in the future, and new people to meet. I don't do change well. I'm just anxious about it.

A few reasons why I'm anxious:

1. It's not my scale. I won't be weighing in on a scale I know. I know that the glass scale I use at home is consistent and I know it is pretty accurate. I'm sure the scale at WW is accurate, but it may still be a shock to see how it weighs me in contrast to my scale at home. What if I'm actually a lot heavier? I know I'm going to just have to deal, but I may have to do a lot of positive self-talk to get myself through.
2. I'll weigh-in fully clothed. Since doing WW online, I've been weighing naked - because I could. This won't be an option at the meeting, so I'm going to have to get over the fact that my weight will be a little inflated due to clothing. I'll try to wear as little as possible (shorts and a tank top), so hopefully it won't be an issue.
3. I don't know how they will treat what I've already lost. I lost the first 50 or so in meetings, the rest on online, but will they give me any credit for those? Will 231.4 still be my start weight, or will whatever I am tomorrow be my start weight? I know it sounds childish, but I want that keyring with all the charms on it, dang it! I earned them!

I know I'm being silly, but I can't seem to stop! Any ideas on how I should deal with it?
