6 months? Training stinks. Depending on where you are, the schedule and people you work with can too. You can transfer. Life takes twists and turns and you end up places you never thought. Usually for the better. I was in your shoes 30 years ago. Only difference was not a lot of flying jobs to be had. I flew 2000+ hours in that time mostly on my own terms. I recently retired and life is great. I still have about 10 years to do 121 flying and more than that part 91. If you really are miserable get out, but I would wait until you are sure it's really as bad as you think.
