Start looking now and Be careful of where you blast your resume to. Tailor your resume specifically to each position you apply to. Use the exact same spelling and phrasing as in the job posting requirements as autobots filter resumes. Only apply to jobs that you qualify, so that you do not end up on a auto-filter list.
For your future well-being look for a company that matches your value system and treats employees well. I know they are hard to find and you may need to move. It was very difficult for me to start looking as I have only worked at Ford, I was afraid. My opportunity requires me to move. I didn’t realize how stressed I was at Ford until the weight lifted when I realized it was over when I accepted job offer. My wife says I am back to my happy silly self.
Some really good advice from @Y60YBeX-ndu .
