If you need to hear this: it's not too late to lose weight, and it's not that hard. Counting calories might sound tedious but with the plethora of apps available it's really easy these days.
The one thing you need to do is consume fewer calories than you expand. Just start there, replace any junk with healthy choices (doesn't mean only broccoli! There's tons of yummy stuff that you can eat, just don't go over the calories).
You don't even need to exercise at first if you don't want to, just count the calories and weigh yourself every morning after the toilet/before breakfast. Look at the number steadily go down over weeks/months, don't stress if it's up one morning for no reason, fluctuations are normal.
Just take it one day at a time and keep educating yourself about nutrition and it gets so easy, trust me. When you realize how good you feel you don't want to stop anymore. After some time you'll probably want to add exercise but it doesn't have to be everything all at once, the most important is to stick with whatever you decide long term and the results will come.
You've got this!
