I was playing a game and Poseidon the Greek god was there and i said an insult towards him and then i become reallyw scarred.
Are you serious?
First, does it matter?
Second, if you call insults praise, I can't imagine what you'd do at church.
a game you say and you insulted this fictional game caracter then no i wouldnt consider it idolatry unless you prayed to the demonic force behind the actual pagan god then yes.
I wouldn't take any boat rides for a while
