The manga and anime have different ending, yes, but the best would be to finish the anime and start reading from there, where the anime ends, the manga however does not, it still continues and carries off from there, I don't wanna spoil anything, But this what I recommend you to do.
Can you tell me what chapter it starts to continue?
Keep in the mind the manga has a few differences compared to the anime. I think this might be obvious, well I guess.
