Being in crisis is when you are not able to cope well by yourself and need additional support from others. If your negative behaviors have been escalating, you're going the "wrong" way and need help blocking that move and moving back the other way to a more secure/usual way of being.

If you cannot currently judge whether you need more/less help, then I would let your T decide when your T wants to move the appointments back to weekly, since it was your T that decided to make the change to twice a week in the first place.
