I used to have really bad health anxiety, recently it has become more of general anxiety but I'm still afraid of stuff like if I might have an anxiety/panic attack, faint, or throw up in public. My family just informed me that we are going to an amusement park this Saturday and I suddenly felt so anxious. I don't even feel like I have full control of my body right now... I'm scared that my thoughts will be the only thing I can focus and I'll be too scared to go on any rides because I'm scared something might happen to me.

How do I calm myself from this anticipation anxiety? How can I manage my thoughts when I get there? I'm scared...
