Self help is such a tricky issue because it depends on where you are at the moment but I think you're off to a great start just by doing those things. Even though self-harm is on your mind your being active in trying to do other things and that's really great.

Generally, when I'm feeling terrible I try to read, watch a movie, or play a video game and let it take me on an adventure so I don't have to really think anymore. Any sort of brain consuming activity works for me though I don't know how good of a coping strategy it really is haha. Being with people is great though. I feed off of other people's good vibes and so hanging out with friends and family helps too.

Sorry this post isn't all that helpful :/ Getting the emotions out on paper or in song is always great but I just like to take my mind off of it.
