I know exactly what you mean. Last week I had a scary experience where I was sitting in class and all the sudden my heart started racing. I panicked and went to the nurse who then had to calm me down from a full blown panic attack that lasted like 40 min. because I could not calm down. Now, I am anxious to go to school every day, and it is terrible. I am fine in all my classes except 2nd hr- the one I had the weird episode in. Every time I go into that class, I immediately feel myself become incredibly nervous, thinking "what if it happens again today oh my gosh what is going to happen today", and for the rest of that week, nothing. then today, exactly ONE WEEK from my first little episode, it happened again. I could feel it coming on and i immediately tried to stay calm and breathe deeply, but it happened anyway, me trembling and shaking all hour
don't know how i'll return to class tomorrow, I'm scared as heck of this thing >.< Being afraid of symptoms is truly a terrible thing, because you almost can't control it, the fear and anticipation are there, and that just leads to symptoms, increasing anxiety and reinforcing your fear of the situation. I wish i could just go to school and have tests be the only thing i worry about again.
and as for the feeling not real thing, been there too. I started experiencing "derealization/depersonalization" a few weeks ago sitting in class. all the sudden, everything felt off somehow. I felt out of place, even with the familiarity of the place. I started to panic because of how it scared me, and i felt lightheaded and thought i might faint. It lasted almost 3 hours but when i got home, all was normal (much to my relief,) i thought that i would never feel right again, or that i was definitely going crazy, and it scared me so bad. but i got home, googled "unreal feeling" and read about all these people who have suffered this and found that it is a common symptom of anxiety and that it most certainly does not mean you are going crazy, you are just experiencing a common thing that many with anxiety have from time to time. I don't want to jinx it, but since i found out what it was and took my mind off of it, i haven't felt it since
just know that you are not going crazy and your anxiety isn't getting worse, you are just feeling a normal part of anxiety, and that is totally normal! If you find yourself in one of these moments, try engaging yourself in familiar things around you. talk to a friend, get involved in the conversation. play a game, read, anything to distract yourself and restore a sense of "normalcy" I remember talking to my friend as if nothing had happened to me, and it seemed to help a lot. Also, some people who derealize like to carry around personal objects or things with texture, like sandpaper or fur. That way they can feel them and say "this is here, so so am i". I remembered that advice in the midst of one derealization episode and quickly began tracing my finger along some Velcro on my bag, and it actually did help me prove to myself that i was really there and not dreaming or something. I know what you mean and i sympathize- hang in there, and just remember to try to relax and distract yourself. the more you are left alone to sit and think and create worries, the worse it gets. but you are definitely not alone in these feelings
