You say your not gay and act like being gay is somehow "worse" than being trans??? Well Im sure many here including me would agree that simply being gay would be a hell of a lot easier that being trans... It sounds to me like you need to do some hard work on accepting yourself.... First of all whether you decide you must transition or not you need to realize at the very least your BI and accept it.... There is nothing "wrong" with that and its never gonna go away for you... When I first started to come to terms with myself and I was still unsure whether transition was right for me I had to deal with this... There were years of self hatred there and a lot of internal shame and guilt about the fact that Ive always been BI but Id never been willing to admit it to anyone much less myself...
Well one day I just had enough and while unsure about whether or not I was "really" trans I knew there could be no more denying the fact that Im BI... I basically had a period of about 2 weeks where I just broke down and "came out to myself" and accepted me as me... Its an incredibly liberating experience... While I knew then I had to start taking steps to transition I was very scared and unsure of where this would all end up... One thing I was then sure of though was that Id no longer live with all the guilt and shame anymore and Id just be me and damn the consequences...
When the time came to come out to family as TG I was asked if "I am gay".... Well I just replied that its a lot more complicated than that LOL, and being trans and very early into transition meant that even to myself I was "super queer"... As things have progressed with my transition and the HRT has done its magic I became more comfortable and confident as woman I more and more became exclusively attracted to men...
I still identify as and accept that Im BI though and again its just totally liberating to just forgive your self and accept it and just be you without all the self hatred and guilt and shame.... Its OK whoever you are to love yourself
