Hi RN, welcome to 3FC!
Not easy to keep on going to the gym or practice other types of exercise everyday, huh. Perhaps you can focus on how well you'll feel after, how it's exciting to see that finally your muscles are growing slowly, etc - little positive things, that make you realize that you're not "doing all of this for nothing" (that's what I was frightened of at first - going to the gym and see no result)? Everything works, walking, jogging, taking the bike, as long as it's a form of exercise. I thought at first that it's not worth it if it's not for at least 2 hours of cardio/weight lifting, but hey, even "only" 30 minutes are better than nothing!
Good luck, and please don't hesitate to e-mail or post here more, you'll find support here, for sure
