New job anxiety!

I finally got a job!

After having to resign from my previous job as a registered nurse in aged care due to harassment, bullying and stalking, I got the call that i have a new job in health admin at a hospital nearby!

Excited to move out of nursing and to see where this ends up at!

But im also getting more and more nervous/anxious as the hours tick by.

I fear i wont be good enough, that ill mess it all up, that i wont get along with the other staff members, that i wont know what im doing, that it wont be what im looking for, that its the wrong choice, that ill let everyone down and so much more!

Ive never worked in health admin but do have some transferable skills after my years of being a nurse. I have no confidence as a nurse, which is part of the reason ive been wanting to move away from nursing. Im just not confident in my skills. But with this position, its less responsibility but having no formal education in health admin scares me! I have no idea what to expect!

Already tonight ive had episodes of nausea, palpitations, a sense of dread wash over me all of a sudden and a headache that hasnt budged since finding out that i have the job over 24 hours ago. Ive thought that maybe i just wont turn up to it on Monday, pretend to be sick or something, make up a story to get out of it. But i know thats not doing me any favours! As much as i want to get back into work, i have so much anxiety around going back!

Im thinking of signing up for a cert 3 in health admin to ease the transition but im not sure if thats the right choice as its full time work im going into. I dont know if ill be able to keep up with the study load even though its online and self paced over 18 months!

I had plans to go to bed early to catch up on some sleep but its now almost 1am and im still wide awake even after my antipsychotic! Ive barely slept the last few months, thought the couple days before i start fulltime work id at least spend catching up on some sleep but instead im here freaking out!

Any advice?

Its times like these i really wish i was on anxiety medication! The antipsychotic for bipolar alone does absolutely nothing for it!😰
