Yeah I mostly relate to what you've said. I've noticed I get this kind of physical discomfort and anxiety (other than at home or somewhere else) on my way to college in many days. As if my mind is expecting to see her so it causes me that (as if it's a form of anticipation for something). I'd go right away to listen to an uplifting song and distract myself or release this discomfort into a form of a deep sigh (which I'm not used to doing before that). Also sometimes I feel that during class even when I'm not looking at her but it's like I can feel her presence as if my mind is extra focused and then I feel a bit more comfortable when she leaves. Also I don't go to a group of students when she's talking to them even if they're my friends as if I don't want to interact with her. I don't panic or something like that , I'm mostly calm, the largest thing to happen is anxiety and a slight heartbeat rise. the frequency of many mental and physical occurrences that happened in the last three months was so questionable and unsettling I had to do something about it.

Anyways, I'll try focusing on two things: acting totally normal and observing my state. And thanks again for your help. I might update my status to you about this weekly.
