it's so good to know that you stopped
SH'ing for a few months. it's okay to slip up everynow and again as long coz you are getting better in the long run. if you don't want your parents to know then thats absolutely fine, don't tell them. As for therapy, do you still go? it might help to talk to your counsellor about it because it can help lay out your feelings. so you know what exactly was going on in your mind and how you can stop yourself from
SH'ing the next time you feel this way.
