I feel for you so deeply as you make your way through some seriously mind altering life changing challenges.
I believe you should feel incredibly proud of yourself for having resigned from your job. This must have been such a tough challenge to meet. I imagine you went through a massive reasoning stage, looking for reasons to stay and reasons to leave. You definitely had a lot of good reasons to leave, in my opinion.
Personally, I can't work with the public. Have worked in the care industry for years, since having established this. While there can be some wonderful people in the world, I can't tolerate angering or depressing people when it's ongoing. You know those kinds of people who tell you how how stupid you are, how ignorant, how bad at you're job you are, how hopeless you are and so on. I think, in working with the public, I'd be the sort of manager who'd regularly be fired based on the advice I'd give to such depressing people, 'Dude, based on your sh*tful depressing self-righteous attitude you've obviously got no filter. Go work on yourself and then come back'. :) Hope I got a smile out of you.
Looking back at my years in depression, which are behind me now, I marvel at how I managed to navigate through the seriously depressing attitudes of people. As a mum now, I also marvel at how my teenage kids manage to navigate through similar challenges. Having come to gradually understand the abilities that come with being sensitive, I say to my kids 'Do not lose your sensitivity', as opposed to telling them to 'Toughen up'. 'Toughen up' actually grinds my gears a little.
I advise my kids to stay sensitive to who's depressing and what's depressing. You'll feel it. Sense who's degrading, who's got no filter, who's got issues, who's inspiring, what's exciting, what feels off and so on. What feels 'off' about someone is something you get a feel for, the more sensitive you become. It's like a gut feeling.
To me, it sounds like you didn't leave a job, you left a paid form of torture. I'm so glad you're out of there. You met the challenge, by leaving. That challenge is now complete. By the way, you're a legend to have made it through. A whole new challenge begins - taking care of your well being and developing your self toward a new job. Whether you need a little time, for a breather in between, is something you may be able to feel.
