Xanax ER giving me panic attacks

Hi, I have been having constant anxiety since I took my Xanax er, usually I have the immediate release that lasts around 4 hours. I’m moving psychiatrists and haven’t had my Xanax for a while which lead to more harmful coping mechanisms, there’s a backlog with getting me into the new places system and they expect by February. My main doctor was out of the country so I got a nurse, this might be where the mistake was made as she had trouble accessing my more protected records.

I had a traumatic experience of an overdose by the hands of my doctor when I was 6, so I’m scared with unfamiliar pills, it took a year before I finally decided to take Xanax in the first place. I can’t stop crying and I’m just relaxed enough to have a panic attack without anyone being bothered, I’m also less tense in general but this is bad because I need to be in control of my emotions as I have a mood disorder. This lead to many panic attacks and bouts of anger and crying, please, I don’t know what this sub really is for but can someone point me somewhere I can find out if I crush the er pills will it be like I took a regular Xanax? Or will I overdose? Is it releasing 2mg at a time or is it releasing 2mg OVER time?

I’ve been looking all over but every site just thinks I’m trying to snort or INJECT that shit.

I don’t want to go to the doctors as I literally can’t control my crying. (I’m not sad or anything just pent up emotions)
