Is it normal to masturbate out of loneliness

I've gotten somewhat experiance with girls but they all ended terribly. One was long distance, so that speaks for itself. Their was a relationship that could have gone off, but it didnt because i was still suffering from the previous breakup, and i realized i was only interested in getting in her pants
-_-

Assuming im not good with any of this, and being reminded of past rejections, i decided to masturbate it out if anything. Somedays its exhilarating, somedays i feel much more alone then I already was, or somedays it ends up just thinking about my ex.....but its all i can do now.
