Welcome, Melsbells. It's so good to have you with us. We're an encouraging & understanding group. I'm not sure where I'd be if not for the support I've found here.
You're very self aware & willing to admit your growing dependence on it. My life would've been so different if only I'd done what you're doing. Be glad that you've taken steps to get free of it. The irritability & edginess will settle down as you adjust to the new normal.
