Cutting yourself to get attention is manipulative if that is the reason you are doing it. That is why Ts often do not react to it. They don't want to give attention to it because that would only serve to reinforce the behavior. Basically, if you are cutting to get a concerned, worried, or caring response from T, then if T gives you that response then you will keep doing it. If I cut, then I am not even allowed to call because I have already chosen the unhealthy coping instead of asking for help to find a better way.
