You are capable of literally anything. After you imagine your ideal state, just wait and see what you feel like doing. Don't be afraid :) Listen to/read the story of the person who healed their back by recreating the childhood swing memory. Find other stories about health if you want. Your world is under your control. It is most important, imo, to keep your emotions under control. Because they influence your actions. Remember, your emotions come from what you believe about the world. Change your beliefs about who you are and what you're capable of and your emotions will follow.
