Oh sweetie, I've been meaning to reply but things have been...not great.
If I added up properly, your appointment is tomorrow which means, if you are anything like me, you're a basket case.
I don't really have much to say other than I understand what you are going through.
I also get really nervous about going to the doctor but mine is more of a needle phobia than anything but I digress. One thing I find is that by the time I get to my appointment, I'm so anxious and wound up that I forget half the things I wanted to bring up. Or I forget everything. So it might help if you print out your post and if you need to you can hand it to your doctor . I'm also suggesting this because you said you were surprised that you could get all that out so honestly -having it written means you aren't required to tell it again.
Now as I ramble on, I'm neglecting to tell you what might help.
- Take a deep breath. I noticed that sometimes I would hold my breath when I was stressed -definitely does not help anxiety. I get annoyed when people tell me to take a deep breath when I'm panicking because somehow it just isn't that easy -they don't understand ___(insert thought of panic). So I try to remember to take deep breaths when I'm not anxious, make a habit out of it so when I am anxious I CAN take a deep breath.
- Slow down. I've always been a fast paced person -I work 60-70 hours a week/I worked full time throughout high school. I have the notion that I am superwoman (not in that I'm fantastic -just that I should be able to "Do it all") and I just need to move a little bit faster. When I can't I get anxious. So another thing I've been working on is literally slowing down. I slow down my pace when I walk, I remind myself that the world will not end if I take an extra 30 seconds to type something up, I don't speed from one job to the next.
- Caffiene -avoid it. I've drank a tea every morning since I could lift the cup. At this point, I can't drink more than that. If I have a soda, a coffee, too much chocolate I will get jittery. I get that body anxiousness without the thoughts that you describe. It feels like I could climb up walls while pulling my hair out.
- Calming music. Sometimes all it would take would be a fast tempo- d song on the radio to get my heart racing. And then my mind would try to catch up and BAM -for no reason at all I was panicking.
I think I've rambled on more than is helpful now. Just know that we are hear for you and I will be thinking about you and hoping you get what you need from you appointment

It will be ok
