I'm leaving school and I want to tell my crush I like them. He knows I like him and probably doesn't want to talk to me after finding out. For god sakes we're the same sex. I'm Pansexual Btw. But anyway I just want to tell him goodbye if I see him tommrow /my last day/ please help I need advice on what to do

You should, just because it's your last day. If he said he likes you back then that would be awesome, but if he doesn't then you're leaving and will never have to worry about it again.
