Panic attacks and general anxiety around use

I’ve finally got my CPAP after months of waiting but every night I’m waking up having panic attacks using it. As soon as the pressure ramps I’m waking up in a blind panic, hyperventilating and tearing my mask off. It’s got so bad that I’ve started avoiding sleep as I’m just so anxious to wear the mask.

I’ve tried wearing it during the day to get used to it but again, as soon as the pressure ramps I start to panic. It almost feels like my mouth is being forced open and it feels like I’m choking.

PLEASE can someone tell me how I can get over this and if there are any useful tips to stop being so scared of using it?
