It is entirely your choice how much you want to disclose. What's important is your health and well-being!

My family has known of my struggles since I was little. Being on meds and continuing therapy has been no surprise to them but they would rather see me alive and functioning than be without. With this in mind, they have even helped when I wasn't able to afford either. I cannot function without the meds and T. With friends, some really close friends know and more do not. For me, unless my disorder affects the relationship and that I feel I can completely trust them, then I may say but it stays on a guarded 'need to know' basis. Then again, a friend of mine does not discuss any of her meds or therapy with her family.

Your family may need some time to consider this development in your life and just as you are becoming educated, they need to learn about you and what treatment really means. They may or may not be accepting even with the new information but it is up to you with what you are comfortable with to ensure your well-being first and foremost.
