Hey there,
First off, congratulations on being a few months
SH free! I know how hard that is to achieve, and you've come so far just by virtue of that!
In regards to your dad, I agree with Jessie that if you're unwilling to tell your dad because you're scared he will send you to the hospital or to therapy, there's a small chance that he will actually do so. Your dad is most likely just concerned and worried for you, like all parents are. He wants to be there to protect you, not to send you off somewhere where you'll be alone with strangers. But, as Jessie said, we're definitely not going to pressure you into telling him in any way because it is your life and your choice. Honestly, I think that he might already know, and he just wants to hear it from you without directly asking. He loves you and will always care for you, and you telling him or keeping it from him won't change that.
Hope this helped and feel free to
PM me if you ever need to talk!
