Fibromyalgia and weight loss strategies

Hi all,
I have been diagnosed with FMS and went through the Mayo fibromyalgia clinic in June of 2023. I also have chronic fatigue syndrome. I know the tools that they gave me to work through this disease, and I have seen success with a lot of them when I can focus on doing them. My main problem, however, is creating and maintaining a balanced life. As a mother of 4 kids, it seems my life is constantly busy with physical and mental demands, leaving very little time for me to "take care of myself". I feel like I am always just hanging by a thread, so when it comes time to grocery shop, plan meals, exercise, meditate, etc, I can do nothing but go lay down.
So I was thinking, if I could at least get my weight down, that alone would give me more energy and less pain on my joints. I am mildly obese, and have put on weight since my FMS started a few years ago. I have done the Mayo Clinic diet with some success in the past, and I know that could work again but I just don't have the time or energy at this point in my life to do it. So I started reading about weight loss injections, and I am wondering if anyone has done them with success? I know they are not a long term solution, but I feel like if I had a better handle on my weight I would be able to focus more on all the other things in my life that need adjusting.
I know that until my kids are grown that life will continue to be chaotic. And until then I will always suffer the consequences of over doing things so I can be there for my family. But I would love to hear if anyone has had success or failure going this route. Thanks in advance.
