Today my teacher was calling on students and I really wasn't paying attention but as soon as the teacher called on me I felt a sharp pain in my head and I began to feel dizzy then my face got hot. Another time I was talking to someone online and I got nervous about what they were going to say so my heart started beating at a really fast pace to the point where I could hear it and my face got hot. Also anytime I'm walking alone by a group of people or by boys that I find attractive in general my legs become all wobbly and I forget how to walk and I end up looking like I'm limping. Also when I'm presenting in front of people my heart beats super fast, I don't look at anyone and my voice starts to stutter. Also anytime somebody Is in my personal space I automatically stop breathing it doesn't matter if the person smells or not I stop breathing till they back off I don't know if it's nervousness or social anxiety.
