I feel your pain. I don't want them to worry nor to think differently of me.

I've hid it for about 10 years and I too am afraid to tell my folks. The only one who knew from the beginning was my best friend who past 7 yrs ago and now, only my boyfriend. He's helped me a great deal. My therapist had told me that I'd should mention to my folks about my condition and therapy I'm receiving but was content that I had support with my bf.
I hope I never have to but if it I do not get better, my bf will come with me to tell them.

Do you have someone very close to you that can talk about it with? Perhaps they can help you for when you decide to open up to your family and other loved ones.

I wish you luck.
I hope
