You are definitely not alone. Honestly I thought I was alone in feeling like this too. I also have a job that I hate more and more each day I go in. It’s a job that pairs horribly with anxiety as I have to answer phone calls and make phone calls — not my forte. But I do it anyway, and my battery drains crazily at the end of the day because of having to be happy and polite all the time.
I’m sorry I can’t help answer any of your questions. I’m still trying to figure it all out myself too. But I relate to you on so many levels.
