Oh the struggle to get in shape is real. Or am I just making it harder than it needs to be?

I know the importance of taking care of my physical health yet it is the area of my life where I fail. I’m really stumped with this one. I can be be an overachiever in every other area of my life but this. My poor body is like, “Uhhhh Queen, I give up!! I just can’t do it captain!!” And then I feel bad right so I jump on the healthy bandwagon but honestly I’m know that it’s coming where I won’t be able to fit on the bandwagon anymore and who wants that? That would just add to the depression at that point. Am I the only one who is at your wicks end? Is there hope? Will I remain obese until the end? I hope I can answer “NO!” to all these but it looks slim to none for me. Lord help me!
