Chein, obviously you should consider you health first and foremost and truly consider losing the appropriate weight for yourself and your family. Firstly because they love you and need you. And secondly to be a good role model.
As far as a solution “in the mean time” suspenders is always an option or you can try using snaps or velcro sewn into your pants and shirts. Suspenders is the easiest way to go. But don’t buy cheap suspenders that will make you look sloppy. Get yourself a handsome pair that you can be proud to wear. Then work on losing the weight. You will be surprised that you might get accustomed to the look and choose to wear them as an accessory even after you lose the weight.
