How can I help him?

so my friend has been acting reaally weird lately and at one point he even said that i’m annoying. so i asked him why he thinks im annoying, and i’m trying to change so i’m not ‘annoying’. one of the things he said is that i point out very obvious things, but i believe i only do that because i don’t really know what to reply to his text. so a few minutes ago he sent me a few photos and i replied something that was really obvious (unintentionally ofc, i didn’t know how to reply). then he replied: ‘wow we got a smartie pants here!!! you want a medal? fck off’ he usually doesn’t act like this so i really want to help him in anyway possible but not sure how.. please help me
