I'm a Cna and love the elderly. Taking care of my Poppy (great-grandfather) with my mom, inspired me to go into healthcare when I was younger. I always used to pick up hours, cover shifts, stay late, go in early.. never said no. For a long time. Then I started getting tired and cranky. Not enough days off. Not enough time to care for me or my home. Money was great but everything else was crap. I had to start saying no.. but it was already to late.. mental decline at that point. Depression started. Major anxiety and panic attacks. Cut hours more till I gave my 2 weeks and then quit that out of desperation. It was h*ll.. didn't work for a few years. Was not at all ready but went back to it anyway. Only made it a year before complete collapse happened again.
It's been 5 years.. I'm going for it AGAIN. I've quit persistent issues I'm in a better place and I know how to say no and have boundaries to keep from killing myself at work. I'm no longer going to cheat lift and break my body either. We have machines for that. So move to a job with the same joy of helping but create better definitions for yourself. Better pay, gas reimbursement. Mileage reimbursement. Overtime. Pay differential for evenings/nights/weekends.
