Hi, I'm 23 & 2 weeks ago my mum finally told me who my father was..
Your post pretty much mirrors a post I made a couple of months ago.. i.e. not knowing where my features came from etc. Well my mum came for a visit & finally caved to my probing & told me who he was.. For example all I wanted for my 21st was to meet my "dad" & call him that.. turns out he was there - I just didn't know it then.. My discussion with my mum presented some ugly truths that needed to be said, and in the end resolved those truths and more..
The bombshell for me was what am I going to do now that I know?! In a way her telling me "joined some dots" (as I'd known him all my life - but not as my "father"), but at the same time raised even more questions that I was by no means ready to tackle. But now, 2 weeks later, I'm trying to convince myself that his role in my life was a minor contribution to who (& in most respects what) I am today. Fortunately for me, I have had consistent strong male role models in my life, so I feel I can't relate in that regard. But at the same time I have trust issues in general, but I think it was more so derived from my mothers keeping such a huge secret from me - more than anything else.
While I can really sympathise with your situation, I suggest you question how the revelation may impact on your life.. others around you aswell - but more importantly your life! From someone whos recently experienced a plight similar to yours I believe it is your right to know where your hazel coloured eyes come from!! (my particular feature was my darker toned skin..lol)
Good luck & i hope it all works out for you.. Thanks, & hope it wasn't too long..
