My illnesses will benefit from losing weight

Options
I am 62 years old and just started living more healthy when I was 56 - I quit smoking and went vegan. Unfortunately the years did their wear and tear on my body and I have back, lung, knee, esophagus and liver problems. All of those will be helped by my losing weight. I started using the MyFitnessPal app to log my food at the end of January and already I have lost 14 lb. The goal is to lose 100. I am being more active now as well. I live thankful for everyday and all things in my life.

How do you add people as friends? When I go to people's page I don't see a button to friend them.
Thank you.
