If it was the cannabis contributing to the anxiety mostly, then yeah stopping for a while should certainly help as any lingering effects should wear off so you'd be back to normal....but if you had anxiety issues before it might be worth talking to a therapist/doctor or something about that, or if you're not seeming to feel any better at all perhaps it would be something worth addressing.

I find it helps my anxiety, but it doesn't do that for everyone that is for sure.
