They are probably doing a fair amount of active ignoring with you right now. You are begging for attention, but you are "asking" for it inappropriately. You seem to be perfectly fine with any attention you can get, even negative attention. They most likely are aware of what you are doing, but until you find a way to ask for what you need appropriately, they will probably not "reward" your negative behaviors with attention because all that really teaches you is "if I hurt myself, they'll pay attention to me and that means they care." That can become a vicious cycle (and looks like maybe you are already in that pattern.)

Have you considered sitting down with them, telling them exactly why you have behaved the way you have behaved, and asking for them to help you come up with a plan to communicate your needs directly and appropriately so you can stay safe and feel more assured that you will be heard without resorting to desperate measures? It would be a win win-win situation.
