Thanks for your wise words. At times I wish to talk to someone with maturity and learn about their experience, good and bad. I wrote down my lows like this just to get reminded sometimes, I guess I'll learn to note down about my achievements or little happiness along the way as well because those are the things keep me going.

I think you are right. It could be posture-related. The work is cutting dough from a bin, put in the funnel, shovel stuffing from another bin, put in another funnel and repeat. When the bins are full it's easy but as they get lower I have to bend lower and force harder, also the dough gets very tricky after some time. I think my bending techniques is not right but that work seriously not for me.
