As a women OVER 300, it didn't really bother me too much, I just always assumed that eventually it would come off. Until recently, when I approached khrussva mentions, the cusp of "losing ability to do normal things".
To me, this was difficulty bending, a lot of lower joint pain, stairs a nightmare, seatbelt at the limit of it's extension, reaching the highest plus size available here in stores (would need to shop online), having difficulty fitting into normal sized chairs almost ANYWHERE, having a hard time standing up from a sitting position, or my personal favorite even having difficulty fitting in the bathtub, then struggling to get up out of it after!Or even reaching myself in the bathroom (sorry if TMI).
These days I really struggle with the diet still - mostly financially and emotionally. I'm a single Mom so have a lot of stress in my life, but each day when I wake up, I say to myself - "just make it through today" - and that applies to all areas of my life
I also have a thyroid issue that seems to not be right. Of course my labs are normal, so the doctor dismisses my concerns but I typically fight to keep from gaining weight - loss would be a bonus! lol
I do plan my meals out so I don't get hungry, and to try and avoid surprises and temptations. Somedays, I'm pretty successful, others not - but my #1 rule is to avoid gluten. This I'm proud to say I've been GREAT at because I have such negative side affects from it (pain, fatigue, and extreme mood swings for one) and because it MAKES ME TERRIBLY HUNGRY (which goes back to being unable to resist bingeing) !!! If I do have a small potato, say, I'm satisified with that - though not low carb, I can stop after eating it, which I cannot say for pasta for example, where I could eat six plates before I'm full.
I'm probably not a person to talk about motivation, most days I wonder if I will ever get to a point where it's effortless but so far for me, it hasn't been. You just really need to rely on yourself to keep going. Find something that motivates you. If you fall off, start again, just keep going, do it again, and again and just don't stop! This is the best thing I can say.
Hope this helps you, best of luck on your journey.
