Only piece of advice that i can give you is......... DO YOU ....... don't DO anybody else... what we all have in common is that we recognized that we needed to lose weight and did something about it. That's where, in my opinion, is where the commonality ends... EXCEPt .. we all want to cross the finish line, whether that's to lose weight or to get off medication.
Everyone's road is different, all paths are not the same.. So try not to compare yourself to someone else's success. Give people an "atta boy", mean it.. and wish them well. That's what we are here on these boards to do encourage each other when we feel discouraged, listen, when folks just want to vent.. offer advice when it's warrented...
Do you! You WILL lose weight, you WILL feel great... and you WILL succeed.. even if this takes longer than other people. I know this sounds so cliche(ish) but.. we all know that the tortise wins the race!
