Hello @Former-Member
Welcome to the forum. The therapeutic aspect can be ongoing rather than simple fact sheets although they can help too. SO many different stories and people and therefore a rich reservoir of lived experience is on here. The understanding of underlying causes was key for me.
I have had a wide range of SH and struggled with my sibs SH. I honestly have only had time to get into specific research about it in last 10 years, before then I had just had to weather the blistering storms of my life, with lots of slipping back ... 4 steps fwd and 2 or 5 steps back!
Healing and moving on from SH can very hard. Tbh I have reduced the major problematic behaviours, but still have residual tendencies/compulsions like mild trichillomania and discoriation disorder which might gross people out, but I am working mostly well with compulsions when I am aware and can catch the thought behind it or the feeling of self punishing.
It is a journey, but know that it is possible to heal both your current wound and the 'instincts' that lead us to cause ourselves harm.
