How to find motivation after 40 yo

Hi there. I am 41, female. So, I have been struggling with weight for the last 10-12 years of my life. Nothing in particular happened, I was in a toxic relationship and started gaining weight. After it ended, I turned to Ayurveda cuisine and have lost great amount of weight, but I couldn’t sustain it long term so after 2 years I started slowly gaining back. Then I started weight lifting and felt amazing, but the scale was the same, however my body was clearly recompositioning. Despite feeling great, it just didn’t stick with me, although I was able to stick to it for a year ( that was 2 years ago). Now I changed my lifestyle (going out less) and moved countries, but I find it way more difficult to find the right motivation and stick to it, especially because the results are slower than 5 years ago. I tried doing Ayurveda again, but the essence I found in it 5 years ago is not something that motivates me now. I just don’t find it realistic enough for the way I am living. How do I move from here and where do I start to make it more sustainable? Any advice is appreciated.
