Arms are Bound

[tauros_asari]

I'm a young woman seriously considering the testosterone treatments.  I've had clues all my life, physically and emotionally, and I think that this may be a good choice for me.  However, the issues with family is holding me back.  My family, although they'll never admit it, is very VERY socially conservative, and I know for a fact that they won't accept this change.  For example, I tried coming out of the closet and telling them I was bisexual nearly a year ago, and my mother doesn't even view it as a "phase", no, she thinks it's a "trend".  Her belief is that I want to be bi because everyone else is bi, and continues to restrict me based on those grounds, urging me to "rise above everyone else and be myself."  My father is not much better, and both my grandmothers would try to disown me if I ever told them. (one nearly disowned her son for marrying a puerto rican woman).  This would all be fine and tolerable if I was not living under the same roof as them.  Not to mention they're urging me to go to college locally so we can "stay close".  If that happens, I'll be trapped in the area forever under their watch.  I can't do that and ever be happy, but going far away will risk tensions and becoming transgendered will likely spark all-out hatred and excommunication, as well as taking away all funding for college and my future, which will be a huge roadblock in continuing testosterone and getting surgeries

I'm still 17 so I know I'm not going to get it done yet, but if I do decide to go with the testosterone, I'm scared that my arms will be theoretically bound due to my family's ignorance.  What should I do to try and lighten the blow, or at least keep my money safe in case they explode as a back-up plan?  Whatever I'm doing now to try and get them to accept my bisexuality isn't working, so I fear for the day (if it comes) when I go trans.
