Thanks a lot for the replies
I have been traveling with mom for the last 2-3 days and she has not broached the topic much since then. Though she keeps on dropping hints about cutting down on dressing, etc, etc.
Well the discussion about sexual orientation etc came out as my mom started questioning about that whether I preferred boys or girls and kind of kept pushing on that. I kind of side-tracked through that as I was not prepared to discuss all that in any sense.
As for the waiting till 30, there are certain important issues which I need to deal with now and right now I think I can deal with waiting till then. But, if it becomes unbearable; then I would transition ASAP.
I was expecting an emotional outburst and the response I have got has provided me a lot of courage and also I feel much better now that I have told me. I love my mom a lot

I don't think my dad and brother will be as accepting but then again I am sure when the time comes I will be able to tell them more confidently
