"What about the social aspect of it?"
The social aspect of it, would be up to you. The only people that should know about your actions on this topic, should be yourself, your doctor, and your SO if you have one. Unless you are nursing in public. And if you do manage it, make sure you wear nursing shields. Otherwise, you might leak through your tops.
"How easily could it be achieved?"
I don't mean to discourage you, but unfortunately it's not easily achieved whatsoever. Even the majority of adopting mother's typically need to supplement with a formula for their children if they wish to try to breast feed. And for cis-gendered women they usually have to start any routines approximately 3-4 months prior to when birth from a surrogate will occur or they know whether or not they will be adopting.
Typical routines try to mimic certain hormone levels of pregnant women, with a sudden stop causing prolactin levels to skyrocket while others rapidly decline, causing the women to have a higher chance of inducing lactation.
I will say, because we are trans and most of us have been on some form of a regimen of hormonal editing, we are more capable than our make counter-parts, but often times less capable than our cisters.
"What about acceptance?"
Acceptance, I can't really say anything about.
"I wish I could pass 100%, but I can't

. I think there will always be something male about me that others will pick up. I wish I was, like, 100% femme, but I'm not

. If I were 100% it would be much easier, but what if I can never be 100% passable? Then what will I do?"
When it comes to being passable or not, just remember all the celebrities that have had issues with some form of the public questioning their gender. Ciara, Kesha, Sandra Bullock; all of them have had a spotlight thrown on them for questions regarding their gender, Ciara and Kesha because of "Hermaphrodite" rumors, and Sandra Bullock for the excess cartilage on her larynx.
"Will I be left at the mercy of adult nursing relationships[emoji47]"
While there are people that enjoy it, that would be up to you.
"I mean, I think I have read that breast milk is able to help with cancer when consumed? Not sure how much truth there is to that."
There are studies that have shown some form of increase in white blood cell count(?) with a correlation to drinking a nursing mother's milk, I don't recall the actual results or purpose of the study.
Either way, discuss it with your doctor, they will be able to determine if it's something you could safely dive in to, if so good luck and keep us updated. It is something you will have to be patient about and my understanding is that it can get rather painful.
I hope I didn't discourage you, I was merely stating any information I currently have.
