Friends needed

Hi I'm scarlet from Nottinghamshire England.
Been struggling with my weight for over 10 years. I put 8 stone on, in two years due to suffering with postnatal depression / unhappy relationship. I started comfort eating big time! Over the years I've lost a few stones then put them back on again. Started using this app, lost 1st 11 so far. Although this is the second time of doing it!
I have a heart problem, I heart is out of rhythm AF
And also beats fast. So energetic exercises are out of the question. Although I have started walking, on flat ground.
Need friends that can encourage me to stay on track. I find helping other also helps me stay positive.
