Hey,
I feel as though I'm in the same position. Honestly, I feel as though it would be best if you gave subtle hints towards your true gender identity. Maybe try to consider buying clothes that are more towards the feminine side and wear it around them. Almost like a little foreshadowing. If you do it right, your parents may have discussions about you and they may or may not confront you about your feelings. Honestly, when you come out, don't make it a surprise to them. If you give them enough time beforehand to see how you truly are, they will have more of a rational reaction.
Also, your friends do not have a burden placed on themselves. If anything, they care about you even more and would be quite happy to help you out. If they're true friends, they'll be there for you.
Hoped this helped
