Three steps forward, two steps back. That’s been my experience as well. Meditation has worked wonders for my ability to cope with the bad days. I try to recognize that it’s effectively just hurt feelings, accept the frustration or shame (or whatever is the feeling), thank those responses for looking out for me, do a little bit of grieving, and reassure myself that I am still learning and that I can do it. The process does work, I think there is plenty of proof of that here. Convincing yourself that it can work for you is much more difficult but logically it must. Be there for yourself and achieve some level of calm and peace before proceeding. You can do it!
