Please help with the understanding of the following sentences. But some of the tears I shed were for the other things I knew I was going to have to change. I’d attempted to quit drinking before, but had never lasted more than a few weeks. And I’d gone up and down on the scale more times than I could remember, but this high number was a new low for me. It turned out I didn’t actually know everything. I knew a little, but not enough to prevent me from getting to this place. I had reached my personal rock bottom, and I didn’t want to know what I would find if I went any deeper. The “one day” I had always told myself I would turn things around by was finally here. Q1: 'gone up and down on the scale' does it physically mean the action of going up and down for many time? or does it mean the weight of the author goes up and down? Q2: 'this high number was a new low for me' The weight of the author is already high, but it will rise from this point to a higher level?
