Anxiety..

I just need to vent a little, I am so frustrated with myself right now 😣. I have always had severe anxiety and no matter how irrational ik I'm being I can't fight the full blown panics I get doing the simplest thing. I need to make an appointment to get an IUD as recommended strongly by my gynecologist. I know I need it and was supposed to make the appointment much much sooner. I've been procrastinating it for a few months because everytime I try to call I start having a full blown panic attack. I'm talking hyperventilating, can't see straight, rapid heart beat, can't even stand level of panic where I lose all sense of thinking or anything around me. I know its ridiculous because its a two minute call to schedule an appointment with a doctor I like for something important but I can't seem to get past typing in the office's number. I just hate this so much. It's embarrassing and frustrating. Can anyone give me any advice or anything? Anyone else with anxiety ever have this problem?

Also just because ik someones gonna comment on this no I can't see a therapist, no I can't afford medication, I have zero insurance. So please don't tell me I need to get a doctors help with my mental health I am aware of that fact I simply haven't found a way to be able to get the services I need.
