Alrighty, I can walk you through the steps if needed. But first a couple of questions, and please forgive me if they are too direct. Are you trying to end yourself because of gender dysphoria? If so, I just want to let you know that HRT can have surprising results. I started transitioning at 19 too (am 21), and I pass quite well to the point where I can go to the proper bathrooms without anyone batting an eyelid. And this is only after 2 years, HRT will work wonders once you give it more time such as 5 years. I would be ending myself due to very complicated reasons that are mostly not related to my own transition.
Anyways, I digress. Since we are both adults I will be providing you with a source (and advice on how to get it from customs) regardless of your answer, but if gender dysphoria is your main reason for dying, then it might be worth your while to stick around a little.
I do have to request a picture of your E bottle with your IGN scribbled on it or a piece of paper nearby, please blur/hide any identifying details (name, address, phone, pharmacy address, etc…) I just need to see the part saying Estradiol-lupin or whichever version of e you are taking, and your IGN in the same picture. My apologies if this measure seems intrusive, we are typically not supposed to be sharing sources with new members.
Do feel free to DM it to me if you feel more comfortable that way.
