No idea how or what to approach anymore

So to keep things short. I’m a 31M. Residing in NJ. After 11 years in the workforce I finally found a job I could tolerate and finally got a small promotion to 24.50 just to be fired 6 months later. I managed to get a quick fill in as an operator for 23.50 to quickly find out I absolutely cannot figure this job out at all as to me it borderlines rocket science but will pretend ALAP for the income. What can I possibly pursue or even try to do at this point anymore I’m assuming not much or to just give up as I kinda already have after 8 years at another job to go NOWHERE according to my peers advice. Fortunately my spouse is a high income earner but would be nice to even make 1/3 what she does. A little reluctant to post here but hopefully some of you have realistic advice that aren’t just buzzwords and pull up by the bootstrap comments. Attached my resume for reference. Thankyou for taking the time to read
