Someday I'd Like To Tel Her...

I'm pregnant with my first child. A girl. I used to self-harm for about 10 years. I have visible scars, one more visible than others. Last year on May 2nd I attempted suicide and almost lost my life to the pills. I spent three days in the ICU and about a month in the hospital recovering. I've come a long way since then and I'm so blessed to have my life. Someday I will want to tell her. When would be the right time to tell her? How would I even tell her? How can I be sure that I tell her without triggering her into doing something like that? And just so everybody knows yes I am healthy now. I see two separate therapists and even since the incident I've been taking off my medications for my great progress. I have no concerns of a relapse or anything like that. Just curious on how I will ever bring this up to her. It will break my heart if I ever find out that she's doing something along those lines like hurting herself.
