Have you looked into the outcomes of children conceived this way?
Regardless of socioeconomic status, donor offspring are twice as likely as those raised by biological parents to report problems with the law before age 25. They are more than twice as likely to report having struggled with substance abuse. And they are about 1.5 times as likely to report depression or other mental health problems.
Could you provide me with your sources for this?
I'm just slightly surprised, as I and many people I know who have donor children have never come across such research - and, of course, as you will know, there is a considerable body of research suggesting exactly the opposite.
There is evidence to suggest that secrecy about a child's origins (whether the child is adopted, donor conceived, the product of sexual violence, etc etc.), is quite damaging. It is possible this may have to do with the fact that families that conspire to keep secrets, especially secrets that cover up histories of abuse, are not the best places to nurture a child.
However, since the OP is single, it seems likely her child will grow up knowing his or her origins from the start.
FWIW my skin in this game is that DD is donor conceived, and it's definitely not a failure. One of the genuinely fun things I didn't expect, OP, is that you get to 'know' another person you've never met - you find yourself recognising 'ooh, that must be something she gets from him!' or 'ah, her face is changing shape again - she looks more like what his family must look like now!'. I always think it's such a nice and interesting thing. I'm not sure if DD will want to meet him, but we know he's out there and willing to meet, and it'd be lovely to be able to say thank you.
