So I'm not currently living with my parents and I started HRT without them knowing. I propably won't see them for a year... I don't think I will be able to hide any changes from them.
My parents love me so much that they call on me every night to check up on me

That makes it harder to tell "I'm their daughter". So how should one explain this? Should I arrange an appointment with my Psychiatrist? I'm worried that they won't understand about my condition, such that a Doctor will have a better success than me

I'm expecting the worst case scenario... My relatives.. Oh God!
Since my religion is Islam I doubt it will be easy. I can picture all my self righteous cousins, Relatives giving me a moral lecture.
They will lecture like how I should devote myself to Allah and this is because of my upbringing. I know, i know my religion says how males can't thread eyebrows, wear jewellery, or be like a woman. I don't believe in any Gods and what I can't stand is Fanatics lecturing me on something their tiny brains can't fathom.
They will tell me to Pray 5 times a day which they find me skipping altogether. They keep telling me I'll be like a Kafir (Unbeliever) and punished by Allah. This gets boring after you sit through the same lecture 20+ times.
I don't know if I can find faith in any religion after what I've been through. I don't know if i have peace of my mind after my transition. But It's certainly beats putting on a fake mask, praying to a made up deity all the while slowly dying on the inside...
