It's a really confusing time and not an easy decision to make.
Have you seen a fertility counsellor yet? I wasn't into the whole counselling thing and only went because we had to, to be eligible for donor. We saw two counsellors. The first one, to be honest, was not very good but the second one was fantastic! Really helped to get my thoughts clear and helped to understand the pros and cons.
And I know I've already mentioned it, but the videos I watched also helped me a lot. Hearing from donor kids themselves and the impact it has had on their lives, the difference between known and anon, knowing from birth and finding out later on in life. I found the videos from VARTA really good and the SBS show as well.
