I see no problem with that as being a 4 or 5 month goal. With the amount you have to lose, losing larger amounts of weight is possible.
Now break that down
start with your diet-- for a week or so track everything (you will probably continue to do that even after) every bite, every taste. Don't really make a lot of changes. the goal is to set a starting point and see where you are. Track using the nutrients as well.
Get off your butt a few times a week. I am not talking a huge amount of exercise, but get out and start walking. maybe so some light weight training. If you are not used to exercise, it will take a little while to get moving.
the biggest thing is find your BIG WHY. Why do you want to get healthy? Why are you on this journey? Find that and motivation is helped considerably.
After the first week of tracking, see where the holes are. maybe it is time to really clean out your pantry, fridge and freezer. maybe it is time to sit and really meal plan. You don't necessarily have to use them, but SP has menus that you can use. They are also adjustable so it you really don't like something just find something else.
Have some snacks ready to go. I find that if i have cut up carrots, celery, and other veggies ready, i am less likely to go other stuff.
Baby steps on your goals--- but the most important one is your BIG WHY.
