I've never had a T who was into making contracts
I imagine though that for some people it makes you feel more secure; that there is somewhere to turn when your head is being overrun with sui thoughts; that it gives you something to hold on to in those moments where it feels like there is nothing to hold
Maybe it also reaffirms that the T cares which could be helpful especially when it's more a case of the thoughts are there but you don't really want to act on them; just don't know what alternatives there are and can't see them
For those where it's beyond that; i don't know that any contract would really be that helpful because there is no reason not to break it if you are beyond the point of caring at all

Is there anything your T could do that would help healed; if the contract idea isn't working for you?
