I’ve re-read your article twice and I have to agree with Diane Nilan (and her colleague Steven).
You give great advice for people who come from relatively ‘normal’ backgrounds with little or no serious trauma. Your article is really great for people looking to understand themselves better and improve themselves.
However, for those of us that have experienced abuse and neglect in childhood, it is very difficult (often impossible) to temper and select which feelings we allow. The trauma we have experienced can only be overcome with outside, professional guidance, which is true in my case. Telling people who fall into the category of experiencing serious, long-lasting trauma to master their emotions is not helpful at best, and damaging at worst.
Maybe a trigger-warning at the start of this article would have helped to set the reader’s expectations and helped readers to understand exactly the types of trauma (and resultant feelings) that this article is aimed at addressing?
