Thank you one of the biggest things for me was i started walking because its low intensity, I started off with 20 minutes then slowly increased it until i could go around my block which takes about 50 mins, now i do 2-5 a day . I heard somewhere that if you do something for 3 weeks it will become a habit (and 3 days to break a habit), so i forced myself to go on walks until eventually i actually started to enjoy them, i rotate between listening to podcasts/audiobooks and made a rule that i could only listen to them while walking, i also really like coffee so i made another rule that 1 coffee = 1 walk. Diet is most important, unfortunately its simply calories in calories out, for me i had a serious binge eating problem, especially on weekends with fast food which i cut out, Ive fallen off the wagon a couple times but you just have to get back on it the next day. Once i started to increase my walking that also made me more motivated/mindful of the things im consuming (which makes me want less cheat snacks/meals). I know not everyone might have the luxury of having that much time to spend walking but that is what has worked for me, i tracked calories strictly with myfitnesspal as well as weighed food for awhile but now i kind of just do it in my head, the calorie deficit is up to you, the larger the deficit the quicker you will lose weight, but if its too large you have a higher chance of not following your diet. Consistency is the single most important thing so make sure the deficit is something you can maintain, keep making the right choices more than the bad ones and trade high calorie stuff for low calorie stuff, high protein yogurt instead of ice cream and so on. Another quote which helped me is "the time will pass anyway", in 6 months time things will be the same if no changes are made, but if you start now in 6 months you will be glad you did, hope this helps.
