Well done for starting! It takes a lot of courage and willpower to change and to keep going!
Don't worry about how you look you are beautiful and now your on your way to being healthy and fit too!
Once you feel you have more energy try going for a sprint or run as fast as you can, get the blood pumping, feel the wind whistle by and possibly do a leap in the air-just because for no reason other than to enjoy it!
That's always my fav exercise routine, I take it to the fields out back where I also go and jump rivers, climb trees and race up some hills then I have a nice relaxing walk to cool down and I listen to the birds
It's important to keep yourself mentally happy too and to enjoy the simple things in life :P
I feel so isolated as every day I search for others like me, I havn't found them yet but I will one day...
