Hi, if you would love to work with children and it would just feel right for you then maybe pursue it.
Even though you dropped out of your Social Sciences course, but loved it before online learning and you can do it regularly again, it might actually be worth going for it again. As the saying goes, “you try once and fail, so you get back up and with work can succeed” or something like that.
If your not really sure on what you want to do later in life, why don’t you look and explore your options. You never know, something else you enjoy may present it’s self.
I suppose just go with what feels right.
