I'm financially dependent on my parents so I shouldn't tell them that I'm trans but I'm not 18 yet and after that too there is around 8-9 years of education-that means I will be dependent on them for such a long time... So I should not come out to them for such a long time? I don't want to be rude to them but they are struggling with so many problems, I don't think they will think of kicking me out of the house now.
Also, I ordered a binder but it never arrived. The seller (maybe) sent a replacement that too never arrived. Someone knows binders that ship to  and reach India?

Not telling them could cause a lot of complications further down the track, especially if they have certain expectations of you as their "daughter". On the other hand, if things are difficult right now, and you aren't taking hormones so there are no physical signs, then maybe you can let it slide until you feel financially secure and are a bit older.
