I tend to be really thin due to my insides hating me (chronic fucking issues with that ish,
will I be able to eat today without it going horribly wrong up until recently, hopefully for the last time) and loving workouts as the best high ever and hating eating food (everything about it is a chore to me and a satiated stomach is not a comfy feeling) but damn, you are the second person here who recently has posted about weight loss and lost more than half my total body weight...
in your case way more than half of me in the past few years, more like 2/3 of me. your current weight loss, about a third of me. that is on both counts, to quote Chappelle; fucking incredible
can't even imagine what it must feel like to have dropped that much weight, that's like seven 10 lb bags of potatoes that you don't carry around anymore. 3 fewer bags in the past 3 months. dang
you must have so much more energy
hope some of it is spent encouraging your kid(s) to eat in a manner conducive to health and join you in enjoying movement. esp the girl(s). granted I grew up adoring heroin chic so there is no such thing as too skinny but for females of any age seeing someone get rightful props for dropping excess pounds can be a bit of a mind fuck, esp for paleface women where there is...no such thing as too thin
one of your kids is vegan right? make sure you include her in what you're doing, being real a lot of women who end up being vegans for conscious purposes start it as an excuse not to eat and come back to the lifestyle/value system after their eating disorder is solved. you gotta be careful with girls in this, in talking with them talk about how you had weight to lose, not that having ribs you can cut paper on is the the goal
personally I think those who shame/make fun of people who are overweight are total assholes but if that helped you...thank yourself. you did this, not the dude who talked shit to you. it's always odd to me when men are assumed to never be body conscious or insecure about looks
as to going at the gym at 6 am, I'm assuming you hadn't gone to bed yet

but either way you're guaranteed to feel so much better for the rest of the day than those who are afraid to move. exercise is better than any drug stimulant in the world for having bright, coherent energy to get through the day
70 lbs over just a few years? unreal, that's...huge and I say that with respect
congrats. keep it up
