Is someone who self harms also suicidal?

Not always, in many cases it can be a way to release emotions. I have been in this situation, I used to self harm as a coping method. I didn't do it because I was suicidal - I did it because it gave me a sense of relief, however I realized the relief is temporary. Therefore, from my own experience, I wouldn't say that everyone who self harms is also suicidal. I believe it's more of a coping method than a way out, as such. I overcame this by seeking therapies and I found other, better ways to manage my emotions.
