I told my best friends about an incident in where I self-harmed recently.
Agreed. I was anxious and scared to share, but I'm glad I did; they were really supportive and it's helped me a lot.
They have, ever since I started taking meds and speaking to my doctor and social worker. This is also the reason why I think you should confide in a professional, it can really turn your life around and you deserve the best!
