Been stressful for me as well, King.
Took a new job 3 months ago. I was so tired of my "iron rice bowl" style position in compliance, doing the same things every month. Took a job as a business analyst - data analytics is where I want to go, professionally - but 3 months in, I'm just not sure that I can hang.
It's a weird feeling. It's the job I want. I knew it was a stretch. The hiring manager knew that I was developmental. I am getting there, but not as fast as I need to to be effective. I'm putting in full days, spending some time in the evenings learning what I can, and just keeping my head down and trying to stay professional. I'm pretty sure that, within another 3 months, I'll have come through OK, or they'll have asked me to leave. We shall see. Changing jobs always carries risk. Shifting careers even moreso. I'm jut doing what I can and wherever the chips may fall I'll be better equipped to handle tomorrow as a result.
