although it was full of learning, it did not give me happiness. I consider it a martyrdom to work in an office 8, 10, 12 hours a day, for a salary that often does not correspond to the effort and time invested,

This is always the case for many people out there, so they tend to overwork themselves,,, and others choose to stay at home. I would do the same if it's my case. I experienced working more than 12 hours at a rate that is not enough to make ends meet if I consider my family too. Maybe enough for myself, but I have other people to feed..
I bet you chose the right path and are in a good situation now. Income may not be stable, but at least, there is a lot of time to relax and enjoy with loved ones..
