Healing is far from a linear process and feeling like we're reversing or going sideways does not mean we are no longer healing.
Even if we not eating well for greatest good, our mind is learning. We are learning to let go of old ways.
Try to have patience with yourself as you learn and trust in your ability to keep keep healing.
When you feel doubt, summon trust...if you can. And if you can't, come here to the forum and ask for help.
