I had a huge burnt out phase about a month back.. Broken car, solo in a very physical, the constrained job, ex was on holiday, so had to reduce work hours to collect the kids etc, then managing 2 kids on top, as well as trying to sort the car.
I've had depression counseling before, and it's really good.. But at times people were asking me for things here, and I felt very close to running away screaming "enough!".
In the end, I went to my bosses and laid it on the line, they brought in an assistant to lighten the load, and the entire 17 strong department chipped in to help as well (in their prep tech).
I paid to have my car dumped at the dealer, keys in with "fix it, if you can't, crush it" on a note. Then I hired a car for 2 weeks.
I adopted the attitude "I can only do what I can do", and narrowed my focus to what mattered.. Nothing non essential.
It's been a month or more..I feel I'm starting to come out of it... Things are level again. Kids happy, car fixed (after the dealer 50% fixed it and I did the rest), I feel the lights are coming back on.
There is nothing wrong with admitting that you need help, and it is hard to stay positive when things seem black. I have a good team and family to back me up, but even at the worst point, I knew I could stand looking at my cabinets of poisons, flammables, and chemicals, scalpels etc, and think "not going to happen". Knowing I could give in made me determined to not do so.
Hang in there.
