Bad reaction from iodine.

I feel so stupid.

I took 1 drop of lugols iodine 5% with a glass of water(1 little sip because it smelled like something extremely chemical)

After that 1 sip my throat started to burn, my legs, arms started to give in.

I started to sweat heavely and got super dizzy which started to trigger a panic attack.

Anyone any advise or experienced something semilar?

Every bit of information is helpfull.
