I've been where some of you are right now. I know well how much it hurts to lose a job you love and how difficult it can be to keep your head up and keep moving forward when it feels like there's no end in sight.
But once I left GF, I realized something: my mental health improved drastically. I felt like a weight had been lifted from my shoulders. I didn't even know how stressed out I was until I was out. My new job has a much better company culture and work/life balance. I'm in a much better position, even if at one time something like that seemed impossible to me. My point is, it really does get better. Just give it some time.
