A month is an awesome achievement!!! Try to focus on that. Just the one thing. I understand the feeling of wanting to fix everything at once but your body is healing. The weight loss and exercise will come in time. It really is ok if you are not up to exercising or if your diet isn't 100 percent healthy right now. Just keep doing what you have been doing.
Our bodies are tired and 30 days doesn't completely fix all the abuse we heaped on them for years. It's ok to be tired. Be kind and patient with yourself.
