First shot

I just took my first dose 2 hours ago I was so so scared and I had an adrenaline or panic attack 2 minutes after. 😭 Im resting now but I still feel so like not off but gloomy or idk how to explain. I woke up nauseous anyway so probably has to do with. Anyone else have this? I even called ambulance to check on me and they did vitals and all.
