Panic about knock on head

I was sparring someone tonight and he hit me on the head a few times, don't really hard but enough to feel it on my head guard. Then I went a bit dizzy but I was also doing a lot of cardio which I'm not used to so now I think I've got a bad injury.

I've got a slight headache but my panic is running wild and I think I'm wobbly which makes me walk as if I actually am, plus I'm shaking my legs with anxiety, pacing around and no desire to eat. I'm listening to some music and going to do some drawing in hopes it chills me out.

I'm gonna try eat dinner but I'm having to take a mouth full and wash it down with water. I've not had a panic attack like this for a long time!!! Just had to write it down also .
