Need some inspiration and motivation

Hi there-sorry this is so long!
Try not to give up. I lost 60 lbs in 18 months, then gained 24 back. I was feeling like I just couldn't get restarted. All it took was a Dr visit where I was told to lose 12 lbs. I don't know why, but I decided I was going to do a workout every day instead of 4-5 a week recommended. If I skip one day then I'd skip 2 and so on. I also decided not to eat after 7 PM. 14 days into this, I realized I had an MFP account from 2013 that I'd never used. So I started to measure all my food and record it everyday (portion control is a big issue for me). I have lost 28 lbs since January 1st. The first 2 months I lost 9 and 7 lbs respectively. But my loss has slowed down some in March and April. My goal is 1 lb a week or 4 a month. That is workable. I am now somewhat "food bored" but am managing to keep the workouts going. When my Dr told me I needed the workouts to reduce stress, I had an Epiphanal moment. Of course it does! I walk about 3.5-4MPH around my neighborhood (5 miles) or I workout on my Gazelle Supreme machine ($250) for 20-40 minutes each time. Music is always a big part of my motivation. I have made several playlists of fast paced and energetic songs. Like you, I am in my late 50's, so I have a huge collection of stuff from the past, and current as well. These playlists have saved my *kitten* in the motivation department! If you can find a way to "just get started" again, it will all pay off. And try to get to a point where you are really working up a sweat for at least 20 minutes.
As far as staying in your calorie range, well, I struggle as well. But it takes a while to learn to "eat small" as I call it. When I lost the 60 lbs, I didn't count calories. But I only ate certain things. Prior, I learned to not have bread, and white potatoes in my house-never! Then I slowly got rid of other things like most refined foods. Pretty much, I lived on Nancy's plain yogurt, westsoy organic soy milk, black beans,raw almonds, bananas, avocados, and Fuji apples with peanut butter. I did eat other things, but since I am lazy and don't like to cook, I was able to buy these items and throw them into a lunch bag easily. I greatly reduced my food consumption at restaurants-to maybe 1x a week. For some reason, I didn't feel deprived or bored...it just felt easy to do. I felt fantastic most of the time-really! I never thought I would like soy milk (this version is just soy beans and water) so much, nor plain almonds either. Now I crave them! Go figure. My Dr gave me the idea to eat lentils (I know...I thought ugh!) but I actually love them more than black beans! I have some other ideas that have worked for me, but this is getting a little long. Just hang in there and keep going:)
