Well I do think that if I tell her and she dies of a heart attack caused by that revelation, that it would most definitely be my fault even if only partially. It's not my fault that I'm trans, but it'd be my fault if I told her and consequently she died, besides regardless of who's at fault, it would be on my conscience forever and I don't think I'd be able to live with that. I am confident that my family won't say anything, they swore they wouldn't tell her anything and I have no reason to doubt them, but of course I do realize that they could still accidentally tell her, especially one of my cousins who is 11 years old, but still I'm not worried.
Kyler, of course I don't want someone to keep referring to me with the wrong pronouns, but what if I tell her and she still does (which I think would be her most likely response). At least the rest of my family wouldn't need to pretend when in front of her, but really is it worth upsetting my grandma when I can still stand her misgendering me? She is already used to me dressing as a guy (I have been doing it for years) but I don't know how much it would "soften" her shock or reaction.
Wow Jess, your grandma must be really perceptive, my grandma is also very smart and wise and I know for certain that she has her suspicions (she even knows - found out accidentally - that I "hide" my birthname). I even remember once having a conversation with her about this. We were discussing my choice of guy clothes and she asked me if I liked "boy stuff/clothes", and I said yes and she insisted and asked again if I really really completely liked and wanted to do guy things and I said yes and she said "well you'll never be completely a guy".
Now that I think about it, maybe you guys are right, I may just have it wrong and she could surprise me, but I know her quite well and sadly I think that'd just be wishful thinking on my part. She always says that I (and people in general) should do whatever I want and wants me to be happy etc., but something like this - how could she ever be okay with it? And I'm not the only one who thinks that, my dad (her son) and other relatives have told me that she won't understand it and that it will be hard on her etc.
I don't want her to be in pain because of me as we're close and I even live with her at the moment - but it seems unavoidable as she will probably find out at some point anyway, and you're right I should probably do it myself before she finds out from someone else. I don't think I'll change at all in just 2 months but in a year or two it's almost impossible that she won't notice, so I gotta think what I'll tell her, the truth or some made-up story. And I can't wait till she passes away like your friend did MsGrace (I find it a very self-less and honourable action btw) as my grandma will probably (hopefully!) still live for another decade at least. Thanks guys for your advice, I have a lot of thinking to do, right now I feel like no matter what I do it's a lose-lose situation.
