i fucked up

Yes depends, if you did it on purpose or not and how long you have seen that picture.

 

I love the tags.
About your question, no if it wasn't on purpose.

 

It depends on how you feel afterwards. If I see porn, even for a second, I feel very depressed after. If I see a nude pic, however, it doesn't make me feel this way.

 

good luck bro

 

"Seeing" a nude picture is not a relapse. Even "seeing" pornography is not itself a relapse. What makes it a relapse is when you see and then choose to look in lust. What makes it a relapse is when you seek out stuff to lust over. I'm getting flashbacks to those lyrics from the intro to A Series of Unfortunate Events.
