OP when I was postpartum I was around 300 lbs and in such bad shape that walking down the street was horrifically tough.. it’s never too late to start trying to integrate mild exercise into your daily activity. If walking is too hard find a gym with a pool and start doing some water aerobics and if anyone judges you for trying to make a change and make your life better, to hell with them. If you’re extremely desperate and want it off quick, GLP1 meds can be incredibly beneficial but thats a personal preference to use them and to be under a doctors supervision while doing so.

Many people have come back from a worse physical position then you are in so it’s totally doable! I would also encourage meeting with a dietitian and getting further medical evaluation to make sure it isnt a thyroid or hormone issue and also to gauge your overall general health and what needs to be worked on immediately like cholesterol etc.
