I got to the beach on Saturday. I love the beach. I think about our trip throughout the whole year because I feel better and I'm happy when I'm at the beach. I think it's the salt, vitamin D, lots of exercise etc. I haven't felt good this week. And today I'm doubled up and extremley nauseous in my room at the beach house. It's so not fair. I'm 16 years old I should be able to enjoy things, especially being at my favorite place in the world, but I don't. And I'm scared because before I left for vacation my doctor said he thinks I have a blockage in me because my legs retain so much fluid/ are so puffy. What's a blockage? What does that mean? Is that even POTS related?
