Do you actually need to lose weight? If so, you just need to be in a calorie deficit. Find out your daily requirements using a TDEE calculator and you can achieve it with diet and/or exercise or even just with tweaks to your eating habits. Even with exercise you still need to look at what you consume as you can't outrun a bad diet! Even walking and a healthy diet will be beneficial.
Are there any park runs or running groups near you? They will have grades of runners, so you can find others that fit your pace.
What about Zumba or Jazzercise? I did the latter, until the classes moved away from my area; I was a runner, but found this used completely different sets of muscles and my overall fitness improved very quickly.
