When I first started, I couldn't stand on my own two feet and feel balanced never mind at harmony. Now I feel stronger, defined, and flexible. At the lowest weight I have ever been in my whole life, even after three beautiful babies. I owe my amazing body to myself. I loved myself enough to make changes I desperately needed for a better life, more fun, and the positivity radiates from yoga and within. No one knows you better than you. The only one telling you that your goal to feel good in your own skin isn't reachable, is you. You have to love yourself now, and later, not just later. Anything you set your mind to you can accomplish. That doesn't mean the first time you try, you will have perfect form, or won't fall out of your pose. But as you fall out of that pose, laugh, get up and try again.
I suggest starting from home. In your living room where it's quite. Meditation first to connect you with the world from within.
