Congrats on your decision. Telling your friends and family doesnt need to be complicated. Cover with a dieting or health change if you need to. They dont live in your personal world, nor do they suffer your personal h*ll. This may very well be the biggest decision you ever make. Dont take it lightly. This disease will kill us! Its just a matter of time! If they push for an explanation, tell them the truth. They will respect you! Good luck!
