I'm a widow... What now??

My husband, unexpectedly, passed away 4 months ago at the young age of 34. We had been trying to conceive for a few months prior. We wanted to start a family and were excited about the prospect. I'm now left with this huge hole where my heart was but I still want to have a baby. Not tomorrow, necessarily, but I'm 34 and I'm worried, with my family history, that if it doesn't happen in the next couple of years it may not happen at all. This is something my husband and I really wanted and I want to follow through with it. I'm afraid if I wait and "maybe" meet someone else some day it might be too late. I've considered using a donor bank and I don't think it's too odd of an idea. Again, this is all new so I'm not talking about doing this right away. Am I crazy?!?
