For one, that's quite a bit of weight! It's not uncommon though to lose weight fast when you are so overweight though, so this is good. Also, I'm excited to see that this lifestyle is working for me! I'm very proud of myself and excited to keep going.
I do have fears that pop up in my head at times though, like last night the thought of "this won't last" popped into my head. I sat for a moment, listened to the thought and then let it go, just like in meditation when you start thinking, you release it with compassion and come back to your breathing.
